I found a P. imparis nest with alates yesterday, hoping to stumble across one soon.
Do P. imparis queens form claustral cells, or do you need to catch 'em the day of their flight?
What else do you think they do? Have Scotty beam them up?
On a more serious note, there was a MASSIVE flight in my area so I now have 8 queens in total, 2 with wings and one 3 queen and one 2 queen colony, wish me luck with them!
EDIT: I'm probably not going to catch anymore since I think 8 is enough
My question was more along the lines of whether P. Imparis forms shallow claustral chambers (that could be dug up), or dig deep straight away.
