Why do moths shake?

Question

i just caught one of those huge moths outside of my door (it was on the ground begging to be stepped on) and it wasn't shaking for a while and it suddenly started shaking, and it got warm on my finger. then i tried to set it on my bed and it flew off (it's under the desk light thing on the wall.) and it's not shaking anymore?

Answer 1

it just happened to me too!

i think its either because they're scared or most likely warning you off..

im not sure, but before i picked it up, it wasnt shaking!

Answer 2

you are thinking of moss.
