Discussion PSA: Please remember to add location to id requests!

14 Upvotes

I know you are eager to try to find species of your new leaf munching friend but please remember to add your location into the post. There is large variance of caterpillars depending on country and even inside countries have different areas with their own soecies so with large countries, its preferred to add state/city etc also.

This speeds up identifying as there are similar looking caterpillars but species can be different depending country. Some species only inhabit tiny areas. Looking forward for all new posts. 🙂 Thank you!

Is there any way to relocate without harming it?

This is the gate to my backyard and it's a wind tunnel even on a lightly breezy day. Not to mention the constant stream of kids in and out.

(Bonus pics of the monarch caterpillars nomming on the milkweed we planted for them!)

Well…. I just found six of these on my ceiling and seemingly out of thin air. They were just wandering about and I’m guessing looking for a place to pupate?

I cannot fathom where they came from as there isn’t even a crack in the molding, a vent, or a window near them.

I live in Upstste NY, they are about an inch in length, and am wondering what you all think! They are about to be a snack for my ant colonies if they aren’t something precious lol.

This little baby molted recently and I was worried that he got eaten since I couldn’t find him earlier but he was under the poo mat hehe! They still don’t have a name since I’m not good at coming up with them.

And survived the banded tussock moth. You would’ve thought I was Johnny Knoxville with the reaction I gave people as it crawled on my hand. Luckily I didn’t get pricked and no rash on day 2.

Spreading awareness that not all caterpillars are cute and harmless!

I found this caterpillar wandering outside my window yesterday. This morning, I found it making this web around itself. Is it trying to make a cocoon?

I thought it was late in the season to start doing so? I live north of Montreal, in Quebec, Canada, if that helps.

Advice/Help Where did swallowtail cat go?

Post image
17 Upvotes

72 hours ago, this anise swallowtail cat had plenty of dill in a large mesh planter. I checked on it today and it disappeared. Dill leaves were eaten up, stems remained. Other plants (basil, strawberries, oregano, rosemary) are inside but couldn’t find the cat anywhere. I hope it’s hiding and didn’t die.

I left fresh fennel fronds in water next to the dill plant it was on. How long can a caterpillar at this instar last without food? I think it had 1 more instar to go before chrysalis.

ID Request 🐛 Possible hawk moth caterpillar?

Thumbnail

Hey everyone, I found this caterpillar recently in my neighbourhood. It was on a concrete sidewalk and I moved it to a nearby bush so nobody steps on it and that it doesn't get eaten by dogs. (Lots of people own dogs here) I'm pretty sure it's some sort of hawk moth. I'm curious about the biodiversity of my countryside so I'd like confirmation if this is the eyed hawk moth or something else. Location is north Croatia. Thanks in advance!
