Activity period in Egypt: Throughout the year.

Remarks: The presence of this species in Egypt was confirmed by Dirickx (1994), who thought that the Afrotropical vestitus was clearly a different species. Curran described efflatouni from a single male caught near Cairo, and considered all of Efflatoun’s specimens of vestitus to be his new species. Efflatoun (1922) stated that this species (as E. vestitus ) is a very interesting fly owing to the fact that it closely mimics the flight of Hymenoptera . It was observed flying above Polygonum equisetiforme at El-Marg. He observed that the adult continuously moves and vibrates its wings, it rests on the flowers for a short time and suddenly darts away and sits on the sand and then back again on the flowers, repeating this performance over and over again. The larvae are bred consistently from onions ( Gendy, 1978).
