eggs on Hickory leaf - Valenzuela flavidus

eggs on Hickory leaf - Valenzuela flavidus
Cross Plains, Dane County, Wisconsin, USA
August 29, 2009
Size: ~4mm for whole mass
Several days ago when checking on the progress of an insect gall on a Hickory leaf, I found this egg mass on one of the leaves. My guess is that these may be the eggs of a bark louse - Valenzuela I believe - which is the only insect I have seen moving around in the container which holds this leaf. The bark louse itself hatched in the container and matured. I had collected this leaf on August 16. There were originally two bark lice in the container but one flew away. I'll keep checking on the progress of the eggs and post any further photos.

Dear Ilona...
May I use this image in a paper I'm preparing on egg guarding in psocids?? I will give you full credit of course. I don't have your full name. This would mean a lot to me ... Thanks

Great series of shots!
Did you notice the female remaining near the egg clutch for any time??? I'm preparing a paper on egg guarding in psocids and I have not examined Valenzuela for this behavior. I know it's been a long time but I'd love to know.

not sure
Can't say for sure that I noticed if the adult was staying near the eggs or not. The adult was not near the eggs in the single photo I have of the entire leaf.

Great catch!
Probably it isn't easy to raise these.
I wonder whether they hibernate or start another generation.

Barklouse eggs
Yes, I was going to call these barklouse eggs before I saw the linked images. Great to have connected these with a particular kind of barklouse--I've seen considerable variation in the silk coverings made by different species, ranging from nearly invisible to completely opaque & resembling a spider egg sac.
