Parasitized Nadata gibbosa

Parasitized Nadata gibbosa
Kennebunk, York County, Maine, USA
September 19, 2010
Size: 3 cm
Based on Wagner's Caterpillar book, I think this is Nadata gibbosa. I noticed that there were numerous black dots on the caterpillar. Are these parasites?

UPDATE: This caterpillar had been in a pupa for several weeks. No movement.

Braconid Cocoon?
I'm thinking that the black dots are where Braconid cocoons were attached and have fallen off.

 
The black dots in your photo...
are exit holes of the braconid larvae. I don't think there's really a visible attachment point associated with their cocoons. Since metrioptera's caterpillar pupated, that doesn't seem to be what we're seeing here. Tachinids often do let their host pupate before emerging, so the Balabans's suggestion may be right... I don't have a better explanation.

Yes, this looks to be Nadata gibbosa
The black spots sometimes mark places where breathing tubes from internal parasites puncture the surface, but we don't see that here. Maybe someone else will recognize them.
