Dasineura gleditchiae

Honeylocust podgall midge

Description

Dasineura gleditchiae is a gall midge species that specifically infests Gleditsia triacanthos, commonly known as honey locust. Native to North America - it is an invasive species in Europe. These tiny insects cause the formation of galls, abnormal growths, on honey locust leaves. The female Dasineura gleditchiae lays eggs on the developing tissues of the honey locust tree. When the eggs hatch, the larvae feed on the plant's tissues, stimulating the formation of galls around them. These galls serve as protective structures for the larvae as they continue to feed and develop. Pupation of Dasineura gleditchiae occurs within the galls. After the pupal stage, the adults emerge from the galls, completing the life cycle. Dasineura gleditchiae typically exhibits several generations per year, especially in regions with favorable climatic conditions. Owerwinters in the soil.
