Sitodiplosis mosellana (Gehin, 1857) - (orange wheat blossom midge)

The gall midge is found in temperate regions of Europe, Asia and North America. It attacks the ears of wheat, rye and barley and the damage results in reduced grain yield and quality. Outbreaks might occur sporadically like in the United Kingdom or more regularly like in Canada and can translated into large losses.

Eggs are laid on the wheat flowers and the hatching larvae move into the florets and feed on the surface of the developing wheat kernels. The mature larvae drop to the ground burrow into the soil, pupate in a cocoon and enter diapause which lasts for 1-2 years but can extend for more than 10 years.
