Tribble Gall

The Trouble with Tribbles

Last year, on October 1st, I posted a BYGL Alert about small, fuzzy, reddish-brown to deep-red galls appearing on oaks in northern Ohio. The sheer number of the fuzzy oak leaf galls last year coupled with their alien appearance drew the attention of landowners as well as the news media once the galls started detaching from the oak leaves to rain down on sidewalks, decks, and parked cars.
