Kite-tailed Robberfly - Machimus atricapillus


Generally larger and greyer than M. cingulatus with a more strongly marked abdomen. There are also differences in details of the antennae and genitalia. The front tibia are largely red and lack the black bands seen in other Machimus species.

Similar Species

Males of this species are readily distinguished by the projecting tab on the last segment which bears a tuft of black hairs. The tab normally has a forked apex resembling a kite's tail. Both males and females can be separated from the similar M. cingulatus and M. coweni by the colour and patterns on the front tibia and femora. See Identification Aids below.
