When I was trimming suckers from under one of my Garry Oaks yesterday, I noticed about a dozen bright red 'galls' along a stem. They looked like miniature cranberries. Hovering nearby was a wasp or hornet. Over the next few hours, I checked the stem several times and found that there was always a wasp (or hornet) crawling over the red bumps. I did manage to open one gall and think saw a white maggot inside but I didn't have a magnifying glass to look more closely. Having lived in Garry Oak territory for many years now, I'm pretty familiar with jumping gall wasps and the galls they produce . . . these are definitely different . . . but what are they?
