About

The Cherry Gall is caused by a tiny gall wasp, Cynips quercusfolii. It can be found on the underside of oak leaves, normally as a single gall. The grub remains in the gall after leaf-fall, emerging as an adult wasp in winter. This asexual generation will lay its eggs on the oak tree trunk which eventually mature to the sexual generation that mate and produce the more obvious galls.

How to identify

How can people help

The Wildlife Trusts manage many nature reserves for the benefit of all kinds of wildlife, from bugs to butterflies, fish to Foxes. But these precious sites are under threat from development, intensive agricultural practices and climate change. You can help by supporting your local Trust and becoming a member; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.
