Greetings from sunny Davis, California! Although I’m on a quest for leaf-mining insects, it’s hard not to get distracted by the diversity of bizarre cynipid wasp galls on the various oaks around here. Today I got to see a torymid wasp ovipositing in one of the spiky pink galls on Valley Oak (Quercus lobata). (See this post for an explanation of what’s going on here.) Every day on this trip I’m finding many things worth writing about, but since I have no time for that at the moment, I figured a few photos are better than nothing.
Added 9/19/2013: This is a “spined turban gall,” caused by Cynips douglasii.
