What's the best verb out there to describe the erratic movement of an insect's legs.
To give you a clearer picture, just think of an upside down cockroach that is 'moving' its legs frantically and quickly because it can't get back on them.
Browsing some dictionaries, I found the verb 'wiggle', but I'm not sure it conveys the sense of agitation that I would like. Obviously I could fix the problem with an adverb, but I was wondering if I could avoid that with a more specific verb.
