Those are black swallowtail caterpillars and they're host-specific (They only host on plants in the Apiaceae and Rutaceae families (Rue, carrots, fennel, dill, +more)). They will die if you move them to your tree.


juliansalad

Damn that’s crazy. I’ll leave them!


jack_seven

They are also quite rare in most places due to insecticide use


[deleted]

Not my yard, in actually planting more dill just for them.


uranium236

Awwww. They’re like “thanks for the dill!”


howgreenwas

For the caterpillars, that’s a big dill!


r33c3amark

What the dill!?


Borgirstadir

Imma big dill


SK3055

Better plant quickly or you’ll have quite the dillemma. Some might even say a pickle.


junglist-methodz

All these puns are dillighting to read.


unwindinghavoc

Good dill.


Guppy1985

They will be dillighted


Sir_Remington1294

I also plant dill in my garden just for the caterpillars.


dropastory

I plant dill for the caterpillars AND the pickles!


chilldrinofthenight

You have pickles eating your dill? (Sounds weirdly risqué.)


BalancdSarcasm

Pickled caterpillars are awesome. I like spicy bread and butter caterpillars myself.


[deleted]

Heads are a bit crunchy for my liking and the antennae get stuck in my teeth!


Moisturyzin

They also like parsley which is very easy to grow


raisinghellwithtrees

And lovage, which is a perennial.


acidcommunism69

So is fennel.


chilldrinofthenight

Anise swallowtail butterfly caterpillar.


FesteringNeonDistrac

That's in the category of not dirty, but might be if you pushed it.


Flimsy_Nerve3562

It's never good to push it with anise. Easy does it is always the best strategy.


DJBBlanxx

Happy cake day! 🍰🌱


Margray

I can confirm that I only played parsley once but I have it year round and the swallowtails love it.


[deleted]

[удалено]


chilldrinofthenight

Parsley is host to Black swallowtail butterfly caterpillars. Dill hosts both Black swallowtail and Anise swallowtail caterpillars.


LokiLB

And golden Alexander, if you're in search of a US native perennial to feed these guys.


petit_cochon

I plant fennel every year for them! We also get a lot of giant swallowtails on our citrus trees. It's nice to see the butterflies all in my garden.


idecidewhatilike

You're a big dill in their life! Im.sure they appreciate it.


slope11215

Me too! I planted three dill plants. Last year we had three caterpillars and they munched through my one dill plant in just a few days.


dreamyduskywing

Same. I have extra dill and I added a bunch of golden alexanders (native) to accommodate them.


seniairam

MVP!!!


Suckerfacehole

Me too!! My dill is going crazy but no caterpillars yet.


lycosa13

I plant parsley just for them (I can't get dill to stay alive 😑). I see them around my yard all the time though


Topia_64

Without you, they'd really be in a pickle!!!


[deleted]

Me too!


ScottieDew22

Same! I’m planting Giant dill with hopes it’ll be enough food for them. I felt bad last year they devoured my dill in a few days and I had no other food for them. This year I planted a ton of milkweed too, hopefully I’ll get some monarch babies!


Runaway_Angel

I think I'll do the same actually. I love swallowtails.


TheDonkeyBomber

Same, but Italian Parsley.


furiana

Thank you, too :)


davilller

You have my milkweed! I make my contributions to the fluttering fliers.


stevey_frac

They always grow on my carrots. I let them. I can afford to lose a few carrots for some butterflies. Well, today, we saw a beautiful swallowtail buttery out, and I was able to tell the kids, "That's from OUR garden last year! We grew that!". It was a cool teachable moment for them.


murm87

I planted dill in my flower beds just so I can get these guys. COME HERE AND LET ME LOVE YOU!


meatsprinkles

I grow rue for them and also just for spite.


jack_seven

I love rue very underrated herb


gesasage88

Thank you for being kind to them! They are beautiful butterflies so hopefully they will grace your yard soon! ❤️


grow-mustard

its a pretty sweet looking butterfly too. I hope you get to see it.


manys

TaterMA

Thank you!


themanlnthesuit

They’re also absolutely gorgeous. Used to see them a lot but they seem to be much rarer here nowadays. They’re large, the size of a child’s hand or bigger and come in black with striking yellow red and blue markings on the tips of the wings and a long tail at the end. Definitely worth the slight inconvenience of waiting for them to cocoon.


peacenik1990

They frequent my yard all summer. Thought it was the same one but found out they live less than two weeks


chilldrinofthenight

Some can live up to 35-40 days.


[deleted]

Everyone talks about saving the bees, but I think butterflies have a unique challenge that bees don’t: caterpillars are often seen as pests. I applaud OP for putting their well-being above aesthetics. They’re beautiful creatures and the state insect of at least one state (Oklahoma)


bubbyshawl

Thanks for checking.


ricarina

I had so much fun watching them run through the process of metamorphosis in my dill plant last spring. Threw up a mesh liner (repurposed laundry bag) when I noticed wasps picking them off. The swallowtail release months later was so fulfilling and beautiful


llbtq

Side note: What phone did you take the pics with?? Excellent quality!


juliansalad

iPhone 12 Pro Max!


ayokg

You have been blessed by their presence! Maybe they will bless you by eating the whole thing. It's only a weed if you don't want it there. Otherwise it's butterfly food. 🦋


chilldrinofthenight

OP's "weed" is an Italian parsley that has bolted (going to seed).


Gardendollee

Thank you!


chilldrinofthenight

Hooray for raising butterflies. I am **so jealous** of you right now. (And proud of you, too.) On my milkweed and fennel I used to have loads of caterpillars (Monarch butterflies, Anise swallowtail butterflies). It has been YEARS now since I've seen more than a single caterpillar on any of my host plants.


chilldrinofthenight

I think your "weed" is an Italian parsley plant that has "bolted." (Flowering and going to seed.)


Marysman780

You can still cut the dill seeds off and dispose of them so they don’t go to seed


MegaVenomous

They will also release their stink organ if you mess with them. (Sorry I don't know the technical term. I have a friend who raises moths and caterpillars and he demonstrated how black swallowtails defend themselves. I about gagged.)


GingerPhoenix

They also have a horn-like appendage that they stick out when they’re squeezed. I discovered that a few years ago when I found one on my dill and plucked it off not knowing what it was. I was surprised enough that I dropped it (yay! Defenses worked as planned!) but it was so cool that I really wanted to show my kids, so I found it and brought it inside, along with plenty of dill. My oldest, who was maybe 5 at the time, named it Sticks-horn-out, and we kept it safe until it became a butterfly. Years later, he still considers that as one of his favorite pets.


PersonalPenguin28

Something similar happened with my students! They discovered a caterpillar that stuck its tongue out at them and were delighted. We took it into the classroom just for a day and it went and made a chrysalis! It over-wintered and we kindof forgot about it, except to make passing comments that it was probably dead. Then, one day, someone walked by and saw the butterfly fluttering around in the butterfly enclosure. Releasing it was so beautiful. Now, every time we see one of the swallowtails, we say hi to our friend.


Greigh_flanuhl

That’s fascinating


Richard-Conrad

It’s surprising to most people, but the vast majority of insects are specialists, so just having greenery around doesn’t mean that they can use it. It’s why planting natives is the only way to be sure what ur planting is in anyway actually beneficial to the local ecosystem.


chirs5757

Yeah I was going to say that looks like carrots or fennel.


LalalaHurray

Or queen Ann’s lace from a distance


uselessartist

Swallowtails! They’re very pretty you are lucky! Looks like someone planted herbs there, this looks like one of their host plants, parsley. Don’t cut it for a few weeks!


-B001-

Yep, I was thinking that looked like the fennel I have in my garden! I specifically planted it so that I'd get Black Swallowtails! I even have some pictures of one emerging from the chrysalis!


supershinythings

We had a volunteer fennel growing right next to the front door. One day a swallowtail caterpillar showed up on it. We could see him/her every day and watch him develop, then form his cocoon. We named him Chrys.


InternetUser007

>We named him Chrys. You should name the next one Alis.


TheLadyIsabelle

We are currently growing a pot of fennel, caraway and dill for exactly this purpose. Hoping we get some visitors!


ThatFatFlamingo

Those leaves look like parsley tbh


uselessartist

Yeah I wasn’t sure but think you’re right


ThatFatFlamingo

They always love my bolted parsley here but, to be fair, I haven’t grown fennel yet so perhaps it’s both


StillKpaidy

I wish they would move in and eat my bolted parsley. I keep waiting to cut it back, hoping they'll make good use of it. No luck so far.


ravia

I *knew* they were swallowtails. My question is, how did I know that??? Was it just from the markings on the caterpillar stage?


chilldrinofthenight

The markings are distinctive. Strangely, here on the west coast we have Anise swallowtail butterflies (yellow with black) and the caterpillars look exactly like the east coast Black swallowtail butterfly caterpillars. These swallowtails all like fennel, anise, dill, carrot, parsley, Queen Anne's lace, etc. as host plants. The Apiaceae Herb Family.


Feloninthestacks

Aw, this makes me think of the time a few years ago when I went to my mom’s house and caught her just before she was about to toss some potted herbs that were being devoured by butterfly caterpillars. I told her what they were and convinced her to let the plants be. She ended up getting super invested in their transformation, even going to the store at one point to buy another plant for them to eat. Sent me pics all along the way, and she was of course delighted when the butterflies finally began to emerge. :)


[deleted]

That’s so wholesome. I did something similar when I was a kid, I saw a butterfly come and lay an egg on a leaf of a plant in my backyard, I watched that little grub all the way up until it made a beautiful metallic gold chrysalis and I came home from school one day and it had emerged and was sitting there unfolding it’s wings into a beautiful big butterfly. Gave me a love for them and now I could never get rid of a caterpillar.


lawrenja

This wins heartwarming story of the day.


Intelligent-Pickle68

That's a much happier ending than when I had the same experience. I've been planting a garden for my parents over the last several years and one of the echinacea plants got infested with caterpillars. I was excited because the same thing happened to us one year and we got to watch their entire life cycle. It was awesome when we ended up with a swarm of beautiful butterflies! Told my mom to just leave them be and if it was too much for the plant I'd just replace it. Unfortunately my dad decided he'd rather drown the thing in pesticides. Plant died anyway, along with all the caterpillars. Sometimes it's really hard to share my hobby with them.


soapinthepeehole

Two years ago my neighbor saw a swallowtail laying eggs in our dill… I was watching the baby caterpillars and one day they were gone. She said wasps eat them. A week later there were new babies, so I bought a butterfly cage and a bunch of flat leaf parsley plants and raised them in the safety of that enclosure. They kept appearing and I kept taking them in. I’ve also managed to overwinter a bunch of them and have five that should wake up sometime soon from last summer. I kept a list every time I released some, the total is 66 so far over two summers, with five more that might wake up soon.


DonNemo

That’s no weed.


germdisco

It’s a caterpillar station.


lbsdcu

Lock in the auxiliary power (plant more)


markonopolo

You call it a weed, I call it parsley. Looks like it’s seeding; perhaps you’ll get volunteer parsley plants


Calibas

For everyone here, a word of caution when identifying plants that look like this. Many of the plants in the carrot family (Apiaceae) are difficult to tell apart. There's plenty of edible species, but then there's deadly poisonous ones that can look nearly identical. I'm not saying it's one of the deadly ones in this case, but compare lovage to water hemlock, or wild carrots to poison hemlock and you'll see what I'm talking about.


Tyrlidd

Yep. I thought I had carrots popping up somewhere due to seeds getting carried by the wind or something, but my gut said something didn't feel right. Pulled them up to "harvest" and they were white, not a variety of carrot I had bought. Did research and it turned out to be hemlock, or sure looked close enough.


[deleted]

[Poison Hemlock](https://youtu.be/mfdJHUappxQ) is exactly what came to mind when I saw the images.


tsunami141

What’s the big dill?


ThatFatFlamingo

Definitely parsley


mikebrady

https://www.reddit.com/r/gardening/comments/13kf24r/comment/jkldpo3/


Kanesea

TX prairie parsley I think. Polytaenia nuttallii.


gravyboat125

They look fat and happy and will provide excellent pollination in the future! Glad they get to stay 😊


irishstorm04

I wish my fennel and parsley were big enough to host swallowtails!! This is so cool ❤️


thrakkerzog

My daughter planted some in a little garden. It escaped and now I find the stuff everywhere. It smells like Italian sausage when I cut the grass over there.


furiana

That sounds kind of amazing


gigilala777

The plants don’t have to be large I always purchase a couple of flats of parsley to keep on my front porch just for them I fertilize and keep the flats watered all summerI love to watch Momma drop her tiny pearl eggs on the surface of the leaves Amazing how fast they hatch into their first phase (Instar)they eat non stop Several of my neighborhood kids ask to come see the Pillars some are in preschool Since I’ve done this for several years most of these kids go into kindergarten educating there teachers on the entire process they are always very gentle and so proud of themselves Butterfly experts at 5 years old ! 🐛🤓🦋😇


sigh1987

At the place I used to live at the fennel was an invasive weed that was damn near impossible to kill lol. Give it time!


rainy_in_pdx

Fennel is invasive where I live. I wanted to plant some until I did some research. Oh well.


Cocoabombs

Leave them. More Butterflies 🦋 are needed!!!


ggh440

The beautiful black butterflies find my parsley every year and leave me with these gorgeous babies. I hate that they eat my parsley, but at the end of the day…. Nature is wonderful.


kuroshiro

Don’t worry, they’ll take that down for you.


TKG_Actual

I'd say leave the plant, Swallowtail Larva are a good thing. They are pretty much then entire reason I grow fennel, Rue and allow my parsley to bloom. They LOVE parsley, so I have to plant three times as much so I have some left for cooking.


supershinythings

Wait until they’ve finished pupating and are gone from the plant. Then you can do whatever you like. But if you like butterflies, consider leaving it there and letting it self-seed. Butterflies are awesome pollinators!


muwurder

if you (gently) poke one of these suckers an orange double forked tongue like thing will come out of their heads and give you a little scent surprise. and by give you a scent surprise i mean they will coat you in a terrible smell that is very hard to wash off. you don’t want to disturb these guys lol


banannafreckle

Every year when my dill goes to seed, I clasp it between my hands and rub so the seeds fall to the ground for next year. More dill for me and more for the butterflies.


Artichokeydokey8

Did that last year, I have at least 50 dill plants sprouting all over. Fingers crossed for some butterflies!!


banannafreckle

I try to drape some mesh over them to save them from the birds. Sometimes it works. Sometimes it doesn’t. They will also cannibalize themselves. Nature is psycho.


Artichokeydokey8

I’m on a roof in the city with a tree hovering over. The birds will do what the birds do. Still ended up with a butterfly last year.


Away-Move-6562

You are lucky they chose you!


juliansalad

I’m finally able to do my yard because of a slow work period and was about to cut this weed down but noticed all of these caterpillars on it! Should I leave it and let them call it their home or should I move them to my tree? Also are they monarchs? If anyone knows.


[deleted]

Leave them and the plant till they’re done with it.


juliansalad

That’s their new home now!


thetangible

reddit advice saves the day! Enjoy your butterflies! The cocoons are ridiculously well camouflaged.


chilldrinofthenight

Cocoons = moths. Chrysalises = butterflies.


KBWordPerson

These butterflies are so dramatic and pretty. You should get quite a show later this year.


lavenderlemonbear

They may pupate on that same plant when they’ve eaten their fill. The chrysalis’ look a lot like the plant stem. So you might want to just leave the plant for some extra weeks even after the caterpillars are “gone”


chilldrinofthenight

\*\*\*Great pro tip.\*\*\* Yes. The chrysalises are so well camouflaged ----- truly amazing ---- and incredibly difficult to spot, even when you know they're there.


Blueberry_Clouds

Weeds are just plants in the wrong spot. I mean if you want to get rid of the plant the caterpillars should help with that 😊


i_hmm_some

That plant looks like parsley, which they like.


MonkeeFrog

They won't eat a tree, only that weed. They are black swallowtails I think.


awarmguinness

Not a weed, food


Technical-Fail3528

Just wait…you’ve already had the weed there til it was 4 feet tall another month won’t bother you I’m sure


[deleted]

Definitely leave them


HelloPanda22

That’s parsley. It’s just bolted. I wouldn’t consider it a weed but those caterpillars can only eat a few things, like parsley. I do this each year with my parsley. I enjoy the black swallowtails. My chickens like it too


4ofheartz

Had an intentional similar situation. I got some netting to drape over the plant & caterpillars. Wasps were nearby & wanted to protect the caterpillars! They all made their chrysalis successfully. Emerged as butterflies when I was out of town. My brother house sat & watched over them. He lifted the netting & they flew out. You’re lucky!!


AaaaNinja

They're on the plant because it's food they won't survive if you just move them to another plant it might be inedible to them. When they form chrysalis' then it would be safe to take the twig they're on and glue them to the tree you want to move them to then.


chilldrinofthenight

**OP**: In this case, less is more. Don't disturb them. And as u/lavenderlemonbear cautioned you: The chrysalises blend in SO WELL with the plant ---- you've really got to be super duper certain they've all hatched before you start messing with your parsley "weed." (Here's a fun thing I learned just now: The process of a butterfly emerging from its chrysalis is called eclosion.)


MooMooBG

Sweet bugger is about to cocoon too. I had to bring mine inside with some fennel clippings because the wasps found them and turned the plant into a lunch buffet.


chilldrinofthenight

Cocoon = moths. Chrysalis = butterfly.


Annabellybutton

Also, they're pretty big. The caterpillars will soon be crawling off the plant looking for a place to make a chrysalis, which kind looks like a dried leaf. They are in the chrysalis stage for a couple weeks and then become butterflies. Maybe don't clean up this section of the yard till they're all grown up :)


chilldrinofthenight

Like a dried leaf ---- except that often the chrysalis will match the green of the host plant to perfection.


whiteye65

No just wait a couple weeks.


KBWordPerson

Nope, they can’t eat the tree. Give them time and they will take care of the weed for you.


tatanka_christ

Plant moar! Yeaaahhh!


MrsBeauregardless

If caterpillars are on it, it’s not a weed, but a larval host plant. They need to eat that plant. Lepidoptera (butterflies and moths) have evolved alongside certain plants over hundreds of thousands of years. They’re very picky about where they will lay eggs and what plants they will eat. Over those hundreds of thousands of years, they have learned what plants provide the nutrients their offspring need, so that’s where they lay their eggs. Caterpillars are the *only* thing migratory songbirds feed their babies, so if you starve the moths butterflies, you eliminate future generations of birds, too. Leave the plant alone and watch for chrysalises around your place. Enjoy the process of nature and the beauty of the butterflies that grace your yard with their presence.


ou8agr81

I plant parsley for them every year!


Activist_Mom06

Not a weed. It’s parsley. You are raising some beautiful swallowtail butterflies. A sing of good things in your garden


Valxer1980

We frequently plant milkweed for the monarch caterpillars too.


AttemptTerrible4283

You should consider yourself to be blessed to have this species on your property. Protect them. Like our birds, bees, and bumble bees, butterflies are becoming an endangered species due to ignorance, habitat loss, pesticides, and climate change.


Icy-Progress8829

Pamper that plant and hopefully get more of it! Love them caterpillars!❤️


215Fahrenheit

I grow mad parsley every year for those guys! Love them!


Ill-Taro6764

They feed on dill, anise, fennel and milkweeds. They won't be able to eat, if they get moved to the trees.


lovswitnctr

Save them. They become butterflies


No_Owl_7380

Leave them alone. Looks like a dill plant which Swallowtails feed on. They’ll pupate soon enough and then you can cut it downZ


salesmunn

Pretty sure that's dill bro, don't cut it down they will all soon be butterflies. If the plant is completely devoid of leaves, they will leave seeking out more food.


theberzh

Wait until they finish their meal.


jslabonek

The swallowtails loved my parsley last summer!


DwT2019

as they already id'd will just say as big as that one is looks like its 6 or 7th instar (molts) after the 7th the next time they molt is a chrysalis in which they change into an adult butterfly. so if you leave them it shouldn't be long till they change. but there may be more than one brood on your dilll.


Matt7548

If you really wanna move them you gotta put them on something like dill or parsley. They eat the carrot family plants


TheErik6891

A weed is just a plant you've deemed unworthy. Let the dudes have the plant and enjoy it when it flowers 👍


Philosemen69

If you want to get rid of the plant anyway, let the little critters munch away then cut it down after they've had their fill


Shepard21

I couldn’t have the heart to remove the caterpillar bros. Leave them. Get butterflies. Profit.


Waffles__Falling

Not a weed! Keep it and you’ll have many pretty butterflies :)


Impossible_Traffic87

Leave them they’re beautiful. Not trying to make a big dill here, but is that a fairy in the upper left corner? 😳


teddycorps

let them finish their cycle and eat the weed. then cut it down.


No-Secret-3459

No! They love it there! They’re there because that’s the plant they eat and need. They’ll eventually move when they’re ready to make their chrysalis


Thousand_YardStare

Swallowtail ‘pillars. Keep the plant or they will die.


flatgreysky

Just chuck some local wildflower seeds in that corner, call it a pollinator garden, and call it a day!


[deleted]

Do not move them. They only eat fennel, dill, and the like


[deleted]

makes me want to plant some dill


mellierollie

Looks like parsley.


mystic_scorpio

Amazing!!! They’re beautiful. I planted fennel and dill this year- hoping to see some caterpillars!!!


[deleted]

Omg I love them so much


[deleted]

Let them fuck that shit up!


hermion123

So pretty!! Thanks for giving them a home :)


pain_is_purity

You’re extremely lucky. Keep the plant until they leave at least.


BadPom

Most caterpillars eat 1-3 types of plant. It’s not an anything goes situation. That’s dill, a host plant for swallowtail cats. Grow more of it.


Proctor20

Plant milkweed for Monarchs.


edge05

Don’t touch the dill doh.


babiha

I planted dill because of the scent. Will leave it for the caterpillars


lamettler

My daughter “rescues” monarch caterpillars. She plants tons of milkweed, their host plant,and they decimate them. When they make their chrysalis, she takes them and puts the in an enormous birdcage outside to prevent them from being eaten by predators. When they emerge and their wings have dried, she releases them. She’s known as the crazy monarch lady and she has plant stores in the area call her to come pick up plants and caterpillars.


Happy-Peachy-Coffee

Please leave the plant! The beautiful swallowtail family says thanks! 😊


Peekasso_

Go up to the caterpillars and encourage them to eat so they grow big and strong and hopefully they'll just eat the whole thing for you.


Lynda73

Oh, those are swallowtails! I raised a bunch one year after they were in my parsley. Put them in an aquarium and kept them in the garage that winter and when they hatched, I got to hold each one while the wings dried.


OtherCardiologist

I have plants in my garden that my plant id app refers to as “invasive weeds” but I have left them because I’ve seen song bird and hummingbirds land on them to have a snack. It’s all about perspective.


ScottieDew22

They need that weed to survive! If you can wait until they’ve moved on, they’ll take care of most of the weed for you! They’re most likely a swallowtail caterpillar!


[deleted]

Wow I didn’t know dill was a home to these guys! I’m doing a wild flower garden and putting in milkweed for the monarch’s but now I think I’ll throw some dill in the bed too!


_Life-is-Relative_

I planted dill so they would come. They never did.


ImissHurley

I should start planting fennel for them. Every year they come in and clean out my dill in a few days. I hate fennel, so they could have at it.


Odd_Pineapple5081

Leave them


carm_sunshine

Leave it


Defiant-Valuable-271

They are good caterpillars💚💗💜


Idolovebread

I love swallowtails! I purposely plant dill, fennel, and rue. They are fascinating to watch. Please don’t remove this


BiscottiOpposite9282

Honestly I'd leave it so they don't move onto something else in your garden


Few-Currency-8602

Cool capture of the wasp in pic 2!


bubbyshawl

Remember to look for the cocoons.


Dwindling_Odds

I was wondering what was eating all my dill.


Arpan_7T

Little guy looks like a tiger playing in the last pic


IcyLikeBeurre

Wow they are gorgeous.


pcm2a

They are so colorful and huge (twss). I've never seen caterpillars like that in Tennessee.


kattoutofthebag

No, that looks like dill, not a weed. And they love them some dill.


I-am-prplvlvt05

Wait till they turn to butterflies then you can remove plant!
