About the foraging behavior of Megachile sculpturalis Smith, 1853, in Mediterranean France (Nîmes and Montpellier) (Hymenoptera, Megachilidae).

Abstract

The study of the pollen content of two samples taken, either on one specimen of Megachile sculpturalis Smith, 1853, or in the lodge of an "insect hotel" frequented by this Hymenoptera, gives preliminary indications on the behaviour of foraging and on the diet of this invasive bee whose first observation in France dates back to 2008. The dominance of pollen assemblages by the pollen of Sophora, an arborescent Fabaceae native to Asia and planted mainly in parks and gardens in France, testifies to the preference of Megachile sculpturalis for this species, at least in the studied area. Further investigations are needed to know to what extent M. sculpturalis prefers collecting pollen on Sophora japonica.
