Summary[edit] Description: NT57 records: Newbyth, East Lothian, Scotland. NT591796 Small slender female Cheilosia without projecting facial hair. Tarsi pale except end segment. Eyes bare. legs partly yellow = 'pagana' group Dark scutellar bristles present so not latifrons. Dull 3rd antennal segment so not pagana and soror. No clear view from above of the facial knob unfortunately so this feature can't be used here to separate longula and scutellata. Third antennal segment paler at tip than base points to scutellata, as does the clear yellow basal tarsal segments. Date: 21 July 2012, 11:54. Source: Cheilosia cf. scutellata (female). Author: S.

Summary[edit] 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.
