Fauna of Montreal
What a great find, and a great series of pictures. In downtown Montreal, no less!

Pardon my ignorance of wasps, but what is the gray disc visible near the top of this photo?

Megarhyssa macrurus
From what I understand, this membrane is actually used to provide some sort of tension/pressure in order for the ovipositor to be driven deeper if needed (amazing evolutionary mechanism). Just yesterday (in Peterborough Ontario) I had witnessed 50+ Megarhyssa (M. macrurus [male and female]and M. atrata females), all laying eggs on their favourite larval host, Tremex columba (Pigeon Horntail wasp). Fresh boreholes from T. columba were evident all over the tree ("sawdust" was covering the low shrubs beside the half dead Beech tree). Really cool to watch so many together.
