Dear Dennis,
I have never studied the species in detail, but in region, NW Spain, they
emerge in July-August (not in fall) and sometimes one can find the last
breeding adults still alive when the first tenerals appear... The adults
breed in March-May, the last ones still fly in July. I have no information
on larval development.

Regards

Adolfo Cordero
