"Here's a project I made a few months ago: A dead fairy specimen in a display case. It was "collected" by the "theoretical anthropology dept" of Aberystwyth University, Wales in 1932. The fairy never hatched as it was killed in its cocoon by a late frost that year. The cocoon itself is comprised of a natural gum-like substance shrouded with leaves and filled with the silk of the pupa."
It's an absolutely brilliant concept that builds on the equally clever idea of insectile fae.
