This is one of the types of leaf cutter bee I get in the garden, the male of this species is quite recognisable due to its blond hairy front legs.
Megachile willughbiella is one of the most frequently observed and widely distributed leafcutter bees in the British Isles. It is found from the Isles of Scilly through Cornwall and Devon northwards, though sporadically, to Inverness, Scotland. Also recorded in Ireland and the Channel Islands. Records naturally are less frequent the more northerly one travels. Despite its wide geographical spread there are still gaps in its current distribution. Mid and north Wales and the north Midlands appear not to support this species though this is possibly a consequence of limited recording activity in these regions rather than a restriction in range. It should also be noted that these potentially under-recorded regions are high altitude which may have a bearing on this species’ abundance and distribution.
Status (in Britain only)
This species is not regarded as scarce or threatened.
Found in a variety of habitats where there is suitable nesting and foraging. Gardens and brownfield sites are frequently visited and used for nesting by this species, particularly in the main centres of conurbation in England.
Mid-June through July and into early August is the optimum flight period for this species.
Polylectic, recorded from Asteraceae, Campanulaceae, Fabaceae and Onagraceae (Westrich, 1989). It is noted by Else (1999 and pers. comm.) that M. willughbiella shows a preference for bellflowers.
Nests can be located either in wood or soil, there is also a record of a nest in a length of rubber hose in a greenhouse (Else, 1999). The cells are constructed from leaves including beech and tutsan.
Bellflowers, bird’s-foot-trefoils, thistles and brambles are all visited by M. willughbiella
