I know that and its other colors exist, but I don't think I've seen a proboscis item, or a mosquito mouthpart item. Insect mouthparts have many shapes in nature. Items with insect mouthparts have tended to be of the whole insect head (like the framed specimens from Esther's). I know that Rosy Maple moths have only vestigial mouthparts, but it would go well with the Caterkiller skin.

These are pretty dang cool. I like this idea.
