Egyptian localities : Eastern Desert: Wadi Rishrash [ Shaumar & Kamal (1978) ]. Activity period in Egypt : March. Remarks : This is a highly mobile species, usually exploiting concentrations of aphids wherever it finds them. Adults are fast fliers, usually within 3m of the ground; they are frequently encountered flying around bushes and shrubs in a slow and purposeful manner, only to speed away after 30 seconds or so. It is to a significant extent anthropophilic, occurring in arable crops, hedgerows, orchards, gardens and conifer plantations. In Europe, it has been recorded visiting an extensive list of flowers, especially the Umbelliferae ( De Buck 1990 ; Speight 2017 ). In Egypt the larvae were seen feeding ravenously on aphids ( Efflatoun 1922 ).
