Winter Dancing Flies

On warm days in autumn and winter, there are thousands of dancing flies or winter gnats (vintermygg) particularly in the windows. Last week all the windows downstairs had swarms of these dancing up and down and were swarming all over the garden too. They are fun to watch and wonder why and how these are active in such low temperatures when most other insects are hibernating or overwintering as larvae or eggs. They can even be seen on warm winter days on the snow. These are flies in the Trichoceridae family (we have 15 species in Norway) and provide morsels of protein in winter for the birds in the garden! The larvae feed on decaying plant material, rotten wood and fungi…there’s plenty of that here!
