This one was on the very same plant, same date, as my previous caterpillar ID request. After an exhaustive search (I Googled it), This one more closely matches examples of the Monarch Butterfly Caterpillar. I think that is what this is, but I wanted to be certain.

Monarch, only found on milkweed family plants.

Thank you sallyg

Off topic question. Are you guys as good at identifying spiders and snakes as you are caterpillars?
If so, I have a bunch to submit. If not, do you recommend any non-FaceBook places to submit them to?

We have a bug ID forum you can post your pics there if you don't get answers here.

Awesome. Thank you.
