Different bud gall on Goldencup Oak (Quercus chrysolepis, Fagaceae)
This is a different gall on Goldencup Oak aka Canyon Live Oak (Quercus chrysolepis) in the Fagaceae plant family. It's a bud gall, different from the stem galls I've shown before. You can see the exit hole where the critter got out. Or did some other critter get in? (San Marcos Pass, 26 October 2012)
I don't know what critter makes this gall, but it looks like the gall of a Cynipid Gall wasp in the family Cynipidae of the order Hymenoptera. It has the same shape but different colors as the Beaked Twig Gall Wasp (Disholcaspis plumbella). Compare this photo.
