What is this mysterious bug?

Question

My mom's friend found this crazy bug in her front lawn. She lives in southern Maine. It is about 4 inches long and has freaky frog-like legs but it moves around like a caterpillar. Any ideas as to what it is?

Answer 1

A sphinx moth.  I am not sure why it is not fully developed.  It could be a developmental error just as occurs in some humans or it could be that when it metamorphosed an injury occurred.  It just did not develop wings as it should have.

Answer 2

it is a type of female moth. i (am pretty sure that is true) but i dont know any more. they look like a moth that lives in NC too. i used to think they were lionants until this summer. give me a little more info, do they have very stubby wings? allot of female moths either cant fly, or have their adult stages as worms.
