Sicus ferrugineus

This fly was very tame and allowed some very close photography just perched on a grass stem. Identification in this case was relatively straight forward. Eliminating Myopa species can be done on the shape of the face; Myopa having a facial extension below the eyes. Two species of Sicus occur in Britain with ferrugineus being the most common and abdominalis much rarer. The two can be told by the size and shape of the theca. When viewed laterally the thecca has little projection and looks more broader than tall whereas abdominalis has more projection and looks as tall as wide.
