Xylota sp.

Flower Fly / Hover Fly

Xylota sp., Hover Fly in family Syrphidae


Family: Syrphidae

Subfamily: Eristalinae



Maier and Waldbauer (1979) studied flies in this tribe, and found that males persue a dual reproductive strategy. In the morning when temperatures are cool and nectar supplies large, these males set up territories in flower patches and wait for females to arrive. As midday approaches, and temperatures rise and nectar supplies run low, the males set up their territory at wet or rotting tree holes, where the females soon come to visit.

Xylota can be a difficult genus to identify from photographs, and it is possible the fly shown here is from another related genus in the tribe Xylotini.
