Distribution. From southern Morocco northwards over the Iberian Peninsula ( Portugal, Spain) to southern France.

Pollen hosts. Oligolectic on Fabaceae   (Tab. 1; Rozen et al. 2010) with strong preference for Loteae (e.g. Lotus   , Hippocrepis   ).

Nesting biology. O. lunata   nests in excavated burrows in rather hard ground with the nest entrances usually being hidden under small shrublets ( Fig. 19 View FIGURES 15–23 ; Rozen et al. 2010; A. Müller personal observation). The nests contain up to 10 brood cells, which are separated by few millimeters only and reach the ground surface. The cells—each constructed within a more or less vertical and about 1.5 cm deep burrow—are three-layered: the outer layer is built of small to large petal pieces of Helianthemum   ( Cistaceae   ) and other plant taxa partly glued together with mud and rarely small pebbles, the central layer consists of a thin and sometimes only weakly developed layer of mud and the inner layer is composed of 6–10 layers of large petal pieces. After egg deposition, the cell is closed by folding the inner petal layer inwards followed by the construction of the cell cap, which consists of two layers: the inner layer is rather thick and made up of small petal pieces glued together with mud and small pebbles and the outer layer consists of a thin wall of several petal pieces tightly glued together. Occasionally, the cell cap is three-layered with a central layer of mud and small pebbles sandwiched between an inner layer of small petal pieces and an outer layer composed of a thin wall of petals. After completion of the nest cap, the cell is hidden below a thin and loose layer of small pebbles and earth fragments.

Behaviour. The males patrol flowers of Lotus   in search of females (A. Müller personal observation).
