Specimen type: Photograph
Observation notes: We first noticed two clusters of these caterpillars (one in a cherry tree in our front yard and the other in a weeping cherry willow tree in the backyard) roughly one week ago. Ultimately, we are trying to determine if these caterpillars are effectively benign or harmful.

Coordinator notes: I would call these an aesthetic pest - typically the tree can survive it, but it doesn't really look nice.
