Caterpillar - Macremphytus testaceus

Caterpillar - Macremphytus testaceus
New Paltz, Ulster County, New York, USA
September 12, 2009
Size: around 3/4"

Tenthredinidae, Allantinae
Macremphytus testaceus. This is the last instar (prepupa) of this dogwood sawfly. The prepupa is a different color than the feeding stages, having black spots such as this. The other picture with which this is compared is not Neodiprion pinetum, but also Macremphytus testaceus.

sawfly larva [not technically a caterpillar]
