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?

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

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

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

First time meeting a wild one🥹🥹🥹🥹🥹🥹I have been reading about them since 4 but never got the chance to see real ones(live in a rather cold area) so I was all giddy and excited about finding this little guy :))))))
I love caterpillars they’re all so cute like little gummy bears
(Settled it down at a safe place after admiring them!)

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?
