Long-Legged Flies

Long Legged Flies

Long-Legged Flies
Left: Mating; Right: Feeding

My trip to Colorado in May 2015 was highlighted by rain every day, 2 hail storms, cool to snowy weather and too early for most insect activity. One exception was a pond in Gunnison, Colorado that had activity in spite of the below freezing temperatures on some nights. Long-Legged Flies (Hydrophorus spp.) were actively skating on the surface of the pond, feeding on other insects, mating and engaged in other Long-Legged Fly activities. These tiny flies move with ease, all six legs in contact with the water.  Unlike water striders, their legs do not create a noticeable meniscus (depression) on the water surface.
