Activity period in Egypt: Throughout the year.
Remarks: Adults highly migratory, usually fly within 2m of the ground. Males hover both singly and in groups, at up to 4– 5 m. When hovering in groups the individual males maintain a space around themselves, chasing off other males which intrude into that space. They are evidently aware of each other’s position however, since when one changes its orientation while hovering, all other members of the hovering group also re-orient themselves to each other. This species usually visits a wide range of white, yellow and pink flowers, from trees to low-growing plants and including nectarless flowers (Alderman 2010, 2012; Speight 2017).In Egypt, the larvae are known to feed on aphids of broad bean (Vicia faba) and potato (Solanum tuberosum) (Efflatoun 1922).
