Arizona Oak Galls, Part 4

Here is yet another type of gall found on the underside of oak leaves in Madera Canyon.

Seven weeks after I collected these, two parasitoids emerged.

The one above is another male Torymus (Torymidae), which may or may not be the same as the one in my last post.  The one below is a male Brasema (Eupelmidae), and according to Gary Gibson, probably can’t be identified beyond that–both because it is a male and because the genus is in serious need of revision.

Nearly four months later, two adult cynipids emerged.

In the meantime another male Torymus had emerged.  Another month passed, and a female T. tubicola emerged.

Finally, after another 3+ months, I noticed a different, tiny cynipid in the vial.

I believe it came from the little cup-shaped gall that was also on the leaf.  Apparently I hadn’t noticed that gall before, or didn’t think it was viable.

It is evidently different from gall #2, being fuzzy and lacking the “saucer.”

I think the host might be Quercus grisea rather than Q. arizonica in this case?
