About Eristalis stipator Osten Sacken, 1877
Eristalis stipator varies in appearance: darker individuals sometimes resemble E. dimidiata, while males sometimes resemble species such as E. arbustorum or E. hirta. Its wings are hyaline, with a small brown pterostigma, and the basal half of the wings is reddish-brown in color. The third tergite is shiny black, and long white setae cover the fourth tergite, forming a distinct band in front of the tergite's posterior margin. The setae on the third and fourth tergites appear to come to a point at their centers. Females have an entirely silvery-white frons, except for a black median stripe that runs from the base of the antennae to the end of the head.
