An alien based off of the wasps I study, the Dryinidae!
The Dryinidae are a family of parasitoid wasps that are ridiculously bizarre and terrifying looking. The females are often wingless (and mistaken for weird ants) and most have these pincer-like claws on the front legs that are used to grapple with hosts while ovipositing. Here’s a good picture that shows this process: http://bugguide.net/node/view/408876
I’ve been playing around with ideas for a science fiction webcomic for younger readers. This would be the mom of one of the protagonists. Still a lot of work to be done on the conceptual design- I’m not all that happy with this- I like the whole “two pairs of arms, one pair of legs” set up, but I’m not too thrilled with the rest of the body- not enough gracefulness, I think. It’s reading too much brute and not enough stealth deadliness. I might get rid of the whiskers/setae and go back to antennae.
Ah well, was fun to do.
