Description and notes

In common with Andrena hattorfiana, the females of A. marginata occur in different colour forms. There are three such morphs in A. marginata: tergites mainly black or blackish-brown (resembling coloration of males); tergites 2-5 of gaster entirely (or almost entirely) pale orange (female of this form figured by Westrich (1989)); and an intermediate form in which the gastral tergites have orange and black bands. The very dark form is apparently dominant in south-west England and in Ireland (but apparently not in Scotland)

Distribution

Local and uncommon though widely distributed in Britain and Ireland. In Britain it exhibits a disjunct distribution, occurring in many of the counties of southern England and south Wales, but being largely absent from the Midlands and northern England. However, it has been collected from several sites in central Scotland (though these are all old records). In Ireland it is known from Kerry, Carlow, Leix, Kildare, Wicklow, West Galway and Cavan. Widespread in Europe, ranging from southern Fennoscandia south to Spain, and east to Russia and Siberia.

Status (in Britain only)

A Notable A species (Falk 1991) (now known as Scarce (Na)).

Habitat

Calcareous grasslands, heaths, moors, woodland and stabilised coastal dunes.

Flight period

Univoltine; mid July to late September.

Nesting biology

No information is available for the British Isles. In the former Czechoslovakia, the females are reported to nest solitarily in both loamy and sandy soils (Kocourek, 1966), though in Germany they nest both solitarily and in small aggregations (Westrich, 1989).

Flowers visited

In addition to the species listed above, the bee visits knapweed (Centaurea sp.), nipplewort (Lapsana communis) and creeping thistle (Cirsium arvense). It is not known if these are pollen or nectar sources.

Parasites

The rare Nomada argentata is a cleptoparasite of A. marginata (Perkins, 1919; Westrich, 1989). The conopid fly Physocephala rufipes has been seen apparently ovipositing on this Andrena in Norfolk (M Edwards, pers. comm.).
