Barklouse - Ectopsocus briggsi

Barklouse - Ectopsocus briggsi
Fairview Park, Costa Mesa, Orange County, California, USA
May 4, 2017


The Wizard of Normal has spoken and ...
"I am quite sure it is E. briggsi. The wing spots and head color pattern are of the right sort. There are no records of E. meridionalis from the Pacific coast."
Guess I was right the first time.

Thanks Diane
I'm not having an easy time telling the difference. The pattern on the clypeus looks more reliable, but the wing markings seem to overlap based on BugGuide images. Doesn't help if they also occur together in the same habitats, as they appeared to be doing so here!

Luckily we have great people sorting them out (you, and Dr. Mockford!).

I'm thinking also...
it could be Ecopsocus meridionalis. I have sent this to Mockford for his opinion.

This one is...
probably Ectpscus briggsi, female. I would have to examine the specimen to be sure.

What sticks out about this one, over the others?
I'm not seeing much between this species and E. californicus. Is it normal for them to co-occur?

Very good question...
according to Dr. Mockfod, briggsi has a pale postclypeus (very front of head) and paler spots at forewing margin. I notice, also, that the abdominal bands in this species are darker and more "even". The distinction between these 2 species is subtle!
