Bagworms found on Swamp White Oak - Thyridopteryx ephemeraeformis
Hillside, Cook County, Illinois, USA
September 16, 2008
Size: about 4 cm long
This Swamp White Oak was infested with these bagworms(150 - 200 best guess). The nearest oak to this one has maybe 50 or so bagworms. At least 5 other trees in the area have a few bagworms on them. Is there anything more that can be done to help identify them?

See Davis, Bagworm Moths of the Western Hemisphere, figure 116, showing the case of Thyridopteryx ephemeraeformis on a broadleaf tree. Size, location, and date are also consistent.
