Distribution.
From
Morocco
northwards to southern
Spain
and southern and central
Portugal
. To the present knowledge,the range of
O. uncicornis
in
Spain
does not overlap with that of the more easternly distributed
O.balearica
.
Pollen hosts.
Oligolectic on
Fabaceae
(Tab. 1;
Haeseler 2008
;
Baldock
et al.
2018
) with strong preference for Loteae (e.g.
Lotus
,
Hippocrepis
); additional pollen hosts are species of Trifolieae (e.g.
Medicago
).
Nesting biology.
O. uncicornis
nests in excavated,
3–5cm
long burrows in loose sandy ground, often in small aggregations (
Fig. 2
;
Haeseler 2008
). At the end of the burrow, one to several urn-shaped brood cells are constructed immediately beside each other (
Fig. 3
). The nest entrance is often near dead plants, whose roots serve to fix the cells in the ground. The cells are entirely made of leaf pulp.
Brood parasites
:
Dioxys ardens
Gerstaecker
and possibly
Stelis ortizi
Schwarz & Gusenleitner
(
Haeseler 2008
;

et al.
