There are 3 species in Oregon. “Okanagana Bella”, “Okanagana Canadensis”, and “Okanagana Rimosa”. All annuals.

Can see the influence of the SW monsoon, and GOM SSTs/Bermuda High clearly in those averages.
FWIW the reason high temps begin to decline here in mid/late July is because humidity is increasing. Dews can peak a month later than temps in strong BH summers.
June and early July are relatively comfortable compared to late July/August despite similar temps.
Nah, these are broods XIII and XIX. Weak emergence here compared to the monster that is brood-X.
In fact many of these broods likely split from brood-X hundreds if not thousands of years ago. It’s likely brood-X was the first/original brood following the end of the last ice age.
