White-Marked Tussock Larvae 5th Instar - Orgyia leucostigma

White-Marked Tussock Larvae 5th Instar - Orgyia leucostigma
Village of Elkhart Lake, Sheboygan County, Wisconsin, USA
August 9, 2000
Eggs (that were supposed to be from the Gypsy Moth) were given to me by a village forester on Oct. 20, 1999. Overwintered eggs in fruit cellar. Eggs hatched July 4, 2000. Fed Paper Birch (Betula papyrifera). On July 16, 2000, when larvae were 12 days old, I started to get suspicious because they didn't appear to look like Gypsy Moth larvae. When they were 16 days old, I
determined that they were White-Marked Tussock larvae... continued feeding Paper Birch. August 9, 2000 (larvae shown in photo, were 36 days old). They pupated on August 13, 2000. Two males eclosed on August 28, 2000.
