Notes on the habits of Blood-sucking Flies observed in Dowa District, Nyasaland

Extract

This species is not common. It is found mostly in native gardens or in gardens now fallow, preferring maize or long grass. It differs from other species in that it does not bite quickly, but “settles” itself first, as though to get a comfortable position for the legs, etc.; also in that it bites with its wings extended. H. vittata is very quick on the wing and is difficult to capture. It seems more prevalent on dull days, and was not found till the rains had well set in and the herbage was some feet high.
