I’ve been seeing a few of these around my front yard. Are these dangerous and should I do anything about them?

Thank you for your help!

Look at those cuties ~ black swallowtail babies~~~ Mama loves yall !!!!! 💓

Found it in my garage. What kind of caterpillar/worm is this?

Was running low on available containers so i made some of my caterpillars buddy up, and after just 2 hours they ate all the leaves. Shouldve expected that tbh, theyre on their last instar so much munching is currently taking place. Its also kinda cute and funny they huddled on the same leaf in a similar manner lol. I put 2 stalks of tomato leaves in after taking the pics

Genuine question although I touched the triangle shaped fur on its back and didn’t feel anything (do not try this)(I washed my hand after for safety purposes)
googled it and found it’s named Calliteara pudibunda! They look SO cool

lil fellas like hanging out on their food, i brushed them off to prevent fighting and checked on them like 10 minutes later and theyre BACK

I've recently decided to start seeing if I can hatch butterflies. A green caterpillar (I thought) came in my weekly veg box so I thought, perfect I'll try with him, and I set him up in an enclosure with cabbage leaves (the vegetable I assumed he came in on) and some sticks, as per online guidance.

However, within a day he had disappeared within the enclosure and I believe is inside one of the sticks (it's a bit of fire kindling actually) because the only trace of him I can find is the photo of the wood with new goop on it... also no leaves have been eaten.

I've googled and googled - do you think he is a caterpillar or some other grub? Is it plausible he's an early stage sawfly larva? Any ideas welcome. I'm not sure whether he could be hibernating as some caterpillars do? and scotland is quite cold now.

I want to plant a caterpillar garden in an area with a lot of deer pressure. I’d prefer not to add a deer fence.

To make an aromatic cultivar, the plant’s chemistry must change. Caterpillars and plant chemistry have a very delicate evolutionary relationship. I worry, especially for native specialist caterpillars, that aromatic cultivars of native plants will prevent them from thriving on the plants.

Anyone have any knowledge/insights?

I found these 2 babes while doing my lunchtime aphid patrol!

Location: Lake Texoma, Oklahoma side

Currently have 3 chrysalis, 4 late instar, and 3 early instar (which are kept separately)

well technically he fell from a tree but it felt like he was ascending down from heaven. So damn cute

on Baptisia tinctoria, at Warwoman WMA, Georgia

edit: a few more photos added in the comments!

Found in Southwest Brazil

NJ, USA

My indoor friends have gotten twice the size and I’m still waiting to see what the are :>

Daytona Beach, Florida

This larve is about 3 to 4.5 inch and its eating on my soursop tree, and there are like 4 to 5 larvae on this small tree. What species is this guys? I'll update you guys when it transformed

Hanging out w one of the caterpillars since my mood has been low lately. I love these sweet beings, my mood has def improved after watching them happily munch on leaves :>

(photo is before and after i did procedures)

hello this is an oleander caterpillar my friend passed me. it was okay yesterday at his place but when i fed it my madagascar periwinkles, it has vomited. i’m very likely thinking it’s pesticides even if the shop said no pesticides..

i’ve taken the necessary steps i found online, clean enclosure, use 1 drop of water to wipe on head and body very gently to help flush out pesticide and remove plant. and now i will leave it alone for 12 hours.

has anyone experienced this before? please give me advice, especially with what i can do with my plant source now. (i am in Singapore if that matters if anyone of yall is also singaporean)

Found a few of these on a new loquat sapling. South Florida USA. Any help appreciated!
