Disholcaspis quercusmamma

Oak Bulletgalls are Rising

Dave Shetlar (Professor Emeritus, OSU Entomology) and I have recently observed newly developing oak rough bulletgalls in central and southwest Ohio, respectively. The galls are produced under the direction of the gall wasp Disholcaspis quercusmamma (family Cynipidae). We're also starting to see the gall's security detail, but more about that later.

They also observed – at a distance – the buzzing security detail protecting the immature gall wasps developing within the galls.
