Just...scrunching up the old body like a dirty sock, I guess
(why are caterpillars like this??)
[img id] Digital art of a monarch butterfly caterpillar in the middle of pupating. The style is cel-shaded with delicate thin lineart. The caterpillar's striped body is split open like it has a seam starting with where the head used to be, with the hard green shell of the cocoon poking out. The caterpillar's stripes alternate chaotically between peach, white, and black, with some transparency showing the shell peeking out of the thinnest parts of the skin. The very top of the caterpillar, its very hind legs are wrinkling up with discarded loose skin. A watermark below the artwork reads 'http://hmcgill.art'. [/id]
