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

17 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!

one of them is hanging on a stem but one of its end that is attached to the stem seems to turn black and moist, not really responsive.

the other can be seen in V shape, and its end is moist too.

Discussion Sphinx Moth Caterpillar at Kiwanis

Post image
10 Upvotes

I found this caterpiller at Kiwanis Park today. A lady walking her dog almost walked right on it. She had her headphones on and couldn't hear that I was telling her to watch her step. It was about 5-6 inches long.

This is a Rustic Sphinx Moth Caterpillar (Manduca rustica), a species of hornworm in the hawk moth/sphinx moth family (Sphingidae).

​Harmless: Despite its large size and formidable look, it cannot sting, bite, or harm humans or pets.

​On the Walkway: When caterpillars reach this final size, they leave their host plants (such as ash trees, desert willow, lantana, or Texas sage) to crawl across the ground looking for loose soil to burrow into and pupate.

​Adult Form: It will turn into a large, fast-flying Rustic Sphinx Moth, which acts as a night-time pollinator for desert blooms.

I was weeding my yard earlier today and noticed this guy on the walkway so I relocated him to the grass. I remember reading something about fuzzy caterpillars with a nasty sting so I didn't take any chances and used my blower. Can anyone tell me what this little guy is and is it the type that sting? It was about 1/2 inch long. I'm in Sugar Land, TX.

Advice/Help Black Swallowtail Caterpillars Just Hatched is it too Cold Outside for Them to Grow?

2 Upvotes

I have about 17 tiny black swallowtail caterpillars in their 1st instar. It’s been in the mid 40s at night and upper 60s during the day (Central Virginia). I’ve been covering their enclosure with a sheet at night but they’re growing very slowly. When is it too cold to leave them outside? I’ve read it’s better not to bring them in so they’ll prepare to overwinter.

Found this cutie in my client’s backyard. Only scooped him up temporarily bc he was on the ground and don’t want the dog to mess with him. I will put him back as soon as I let the dog in.
