Excavator: Dead wood. This species is unique among British Anthophora in excavating its nesting burrows in dead wood, including trees, fencing and even driftwood on the shoreline. A nest usually consists of two or more parallel galleries. The cells are oval in outline and are initiated as enlarged sections of the burrow. The cell wall consists of fine, compacted wood dust which is chewed from the wall of the burrow immediately preceding it, thus widening the latter to make room for another cell. The female has, therefore, always two cells under construction, one which is being lined with wood dust excavated from the succeeding cell-to-be. The lining of the last cell is taken from the sides of the burrow just within the entrance and this is the reason for the considerable widening which is present at this point (Nielsen, 1902). Nests are figured by both Nielsen & Schulze (1923), and Müller, Krebs & Amiet (1997). The nesting biology of its sibling species, A. terminalis, in Canada is described and illustrated by Medler (1964). He found that the cells of this species have a whitish, glazed, hardened and impermeable lining, no doubt made from a salivary secretion which is applied before the cell is provisioned with food. It is possible that the cells of A. furcata are treated in the same manner. In A. furcata, The winter is passed as a prepupa, not contained within a cocoon (Else & Edwards, 2018)
