Ficus_glumosa_stem_galls.jpg

Ormyrus (Ormyridae) leaf petiole/ leaf bud galls.

Ormyrus species (Ormyridae) have been reared from these petiole/ leaf bud galls on Ficus glumosa, but they may or may not be the primary gall former. The Ormyrus species could be parasitoids or inquilines of Eurytomidae or Epichrysomallinae that instigated the gall formation (personal communication by Simon van Noort).
