The Twin-spot Centurion (Sargus bipunctatus) is a European species of soldier fly.
The male and female of this species differ considerably in appearance.
Males are very slim with a metallic green thorax and metallic bronze abdomen.
Females have a broader build with the base of the abdomen extensively reddish/orange.
It differs from the similar looking Chloromyia formosa in that its eyes are not covered with dense black hairs.
