Parasitoid Wasp (of Pieridae?) - Trogus

Parasitoid Wasp (of Pieridae?) - Trogus
Tweed, Hastings, Ontario, Canada
Size: ~ 17 mm
Chrysalis (Cabbage White?) was collected in mid-summer, between 1995 and 1998 inclusive. I told my daughter a Cabbage White butterfly would emerge in a few days. She was quite disappointed and I was surprised when a red wasp rudely chewed its way out.

Moved from Trogus pennator.

The scutellum looks like it may be more pyramidal, which would be more indicative of T. vulpinus under the recent revision. Other traits are primarily visible under microscopy. Both species also share a number of hosts, to add to the complications.

Chrysalis is surely that of a species of Papilionidae. The known hosts are listed here.

Moved from Braconids and Ichneumons.

I guess it doesn't matter now that the wasp has been identified, but I uploaded images of its wings. P. glaucus, P. polyxenes and P. troilus all range in my area with P. troilus being uncommon. Too bad the chrysalis was attached to brick wall, a host plant might help narrow down the butterfly species. The length of the chrysalis is 23 mm.
