Flyday: Helophilus trivittatus

Today another fly with no common English name: Helophilus trivittatus. The Dutch name for it is citroenpendelvlieg. It is one of the four species of Helophilus that fly around in the Netherlands. All four look very much alike, but this one is the largest. In addition, the yellow markings are paler than the other species. Other clues are found in the white markings on the abdomen and the yellow line on the face (not visible in this picture). Unlike in previous Flyday flies, there is no real difference in eye positioning between the sexes.

Larvae live in nutrient-rich waters, where they feed on bacteria and dead, organic materials. Mature flies sip nectar. Some sources indicate that these flies head down south at the end of the summer, possibly to maximise their summer experience. Smart flies!
