Cheryl

may I use this image (with proper credit to you) an a paper I am preparing on egg guarding in psocids? You don't know how much it would mean to me.

I was so glad to see this image!

I am studying egg guarding in Ectopsocus meridionalis and I plan to look at E. californicus too. Your image tells me that californicus also lays eggs in clutches and this female just may be guarding her clutch.

Family Ectopsocidae

I agree that it looks similar. To me the lack of a Cubital Loop places this small clear winged Psocopteran in the Family Ectopsocidae. In Canada we have two species in this family both from the genus Ectopsocus but I am not familiar with identification characters for this family so I will leave it at the Family level for now. Cheryl your Rhododendrons seem to be a popular hangout for Psocoptera.

I always look for them there

I find them under the English Holly leaves, too. I wonder if it has to do with the fact that they both have evergreen leaves.
