Hi Chris,
Sorry,I totally misspelled the first name of the Skeletonizer. It should
be Grapeleaf Skeletonizer(Harrisoina americana). I've been using
Bugguide.net as a reference for this sighting and the pics discriptions on
that webpage lead me to my conclusion.

What species is this? In Nova Scotia, we only have three species in this
subfamily, Ctenucha, Ciisseps, and Lycomorpha pholusDrury which looks quite
different.

I'm not an expert of this group but as far as I'm aware the diagnostic
difference between Cisseps fulvicollis and Ctenucha virginica is that the
former species has an large and prominent translucent patch on the hindwing
(this is very obvious). I don't think that there are diagnostic differences
in the orange collar, or the bluish tinge or thickness of the pronotum. It
sounds to me like your specimens are Ctenucha virginica.

Whatever this is, I don;t think its found in Nova Scotia.

Great: thanks!
