Aquilegia Gall Midge

Macrolabis aquilegiae

Aquilegia Gall Midge

A bouquet of flowers
An Aquilegia Gall Midge is a tiny fly, measuring only 3mm. It's the larvae which cause most of the problems. A female fly will lay her eggs on the undeveloped buds of Aquilegia. Upon hatching, the larvae begin to eat inside the bud and this causes new growth to become malformed, creating plant galls. Galls prevent the flowers from opening properly, so this is a good indication your plants might be infested by this midge.
