I think that's referred to as a "mangina". Oddly enough, Mangina is also the name of a rare asian species of moth, a feature of the film, though not the same breed. I suspect the writers of the film had some knowledge of the16d0 irony.
Got to give him props for doing that, and the whole "Hey Vern, I'm Ernest" routine he pulled in this movie. Jim Varney should have been proud.
