Pogonortalis doclea, the boatman fly, is a species of signal fly (family Platystomatidae).[1][2][3][4] It is native to Australia and has been introduced to California in the United States.[4]

Description[edit]

Characteristics of the genus Pogonortalis are: the cheek immediately below the eye being less than a tenth the height of the eye; the hind femur having an anteroventral keel at the distal third; and the anterior crossvein of the wing meeting vein 4 before the mid-length of the discal cell.[5]

Pogonortalis doclea is sexually dimorphic. Males have a bundle of long curved bristles on each cheek of the head. In this location, females have a single shorter bristle among small hairs. Larger males also have the head ventrally widened.[6]

Behaviour[edit]

This species waves its wings like the rowing of oars on a boat, thus the common name "boatman fly".[4]

Pogonortalis doclea is commonly found in Australian gardens. Adults are attracted to and feed on the fresh dung of mammals.[5]

Males engage each other in face-to-face pushing contests.[6]
