Definite Tussock female - Orgyia definita - female

Definite Tussock female - Orgyia definita - Female
Town of Baileys Harbor, Hidden Corners Sanctuary, Door County, Wisconsin, USA
September 20, 1997
Found larva on Tamarack (Larix laricina), but it switched to another unrecorded food plant after I captured it. It pupated and when “something” eclosed, I thought it was a parasite, so never considered taking a look at the photo of the larva. Several years later, I took the slide to a meeting of the Wisconsin Entomological Society. The experts thought it was the female Orgyia leucostigma. I did not bring the larval photo, thinking it was NOT a Lepidoptera. Recently, I shared this photo with Bob Patterson of MPG, he questioned the ID and wanted to know if I had a photo of the larva. After searching through my archives, I discovered that this specimen was actually from the larva of O. definita. The eight-year mystery was solved. I have also included the larval and cocoon photo on this website.

Definite Tussock female
Janice J. Stiefel...Thank you for your interest in these mysterious, intriguing and deceptive insects. This species has been a real eye-opener. I try to keep an accurate record in my data base of all that takes place, but occasionally I forget something. If Bob Patterson hadn't questioned the ID, I would have gone on thinking it was the White-Marked Tussock female and probably would have never dug up the larval photo from back in 1997. Have a Merry Christmas, John and Jane.
