Nice to see someone else photographing cynipid galls!

 
Fascinating Subject
Thanks for your acknowledgment and contributions. Since I discovered plant galls last September, I haven't been able to think about anything else.

 
addictive
Yes, cynipid galls are very addictive. They have distracted me from beetles. :)

Since you're in the Bay Area, do you know about this Marin CNPS gall hike (Aug 12) with Kathy Schick?

 
Guided Gall Hike
Thanks (again). I had no idea. I'm putting it on my calendar; and, look forward to meeting Kathy.

Also, your editing of this page prompted me to view YOUR recently submitted images–which enabled me to quickly identify a soldier beetle I photographed last month! So, I know what you mean about 'beetlemania': last year I discovered (as in 'Columbus discovered America') the lifecycle of Lady Beetles (see my contributed images); and, I'm hooked.
