Liposthenes glechomae

Liposthenes glechomae is a cynipid gall wasp that causes galls to form on Ground-ivy. The galls are globular hairy swellings on the undersides of leaves or apparent on both sides of the stem. They are green or reddish in sunlight, soft at first becoming hard and containing a white larva. 

It is a unisexual species, with males rare or absent; the females reproduce by parthenogenesis.
