What is aquilegia gall midge?
There is currently no control for this insect other than the removal of infested flower buds. This should be done regularly, to remove larvae before they have completed their feeding and exited the flower to drop to the soil. Damage by this insect comes to an end during June, with later flowers escaping unharmed. This midge is specific to aquilegia and will not affect any other plants.
This midge has only one generation per year. Adults emerge in the spring and lay eggs on the developing flower buds. The larval feeding period is likely to be short, occurring over a few weeks in May and June, after which the maggots drop down into the soil to pupate.
