She's loosely based on a California leaf-nosed bat, which eat bugs.

Aha! I said I would have another go at drawing that Literal Batgirl - and now you can see I wasn't joking when I said she looked completely different in my head! This is pretty much exactly how I imagined her - but I'm still not sure if I got the amount of thickness right. Anyway, I spent many torturous hours perfecting the anatomy and proportions, but when it came to the colouring, the shading I tried didn't work, so I kind of fudged it and stuck a paint texture on it.Anyway, now the colours are right, the hair is better if not perfect, the body proportions are closer to how I imagined, that neck fluff is gone... she just looks closer to how I imagined. And the personality is showing, too. This drawing was basically, besides cementing what, um... the bat lady looks like (she needs a name), an exercise in foreshortening (mainly with the arm), so the whole apple thing was just improvised and it's not supposed to be... I guess, "good". Whatever. What I just wrote makes no sense, but I'm trying to watch Game Grumps as I write this.Sketch (with extra cute bat doodle):
