Anasimyia contracta (female) - Flickr - S. Rae (2)

Description:

Description: Cowden Pools, Midlothian, Scotland. Fordel, Midlothian, Scotland. My first experience of Anasimyia hoverflies, a genus associated with bullrushes. Not an easy genus to sex as both sexes have separated eyes. Two species in Britain have neat little rounded, lobed comma-shaped markings on the tergites - contracta & transfuga. Only female contracta's abdomen has a distinct waist at tergite 2 bulging at tergites 3 & 4 as shown in the above photo.
