Roosting on dead hardwood.

super!
where i grew up, P. fennica were hanging out on Ptilinus-infested dead trees

 
First Guelph encounter
Several years ago in Toronto, I observed both host and parasitoid milling about on a hardwood, seemingly ignorant of one another...

 
timing
What time of day did you encounter them out on the trees?

I swept one from forest edge vegetation weekend before last. The forest has about a dozen standing dead debarked (at least partially debarked) hardwood trees that are borer riddled and have Teretrius, passandrids, anobiids, weevils, wasps, and sometimes Zenodosus milling about on them. I have yet to see one of these on one of the trees. I was out for the better part of this last Saturday mostly inspecting these trees and nada. Just wondering if it's a time-of-day thing. :(

 
Late afternoon
Jeff, my image date stamps indicate ~3:30-4:30, although the individual imaged was one of several found roosting at night. Here in Ontario, I've encountered Pelecotoma from late-June to mid-July. Your detailed description of the dead standing hardwood fauna sounds nearly identical to what I also noticed wherever Pelecotoma occurred.

 
cool
Thanks for the info. I left the woods around 3ish. They probably all came out to play then. ;-)
