Distribution.
From
Turkey
eastwards to central
Iran
and southwards over
Syria
and
Lebanon
to northern
Jordan
.
Pollen hosts.
Oligolectic on
Fabaceae
(Tab. 1;
Özbek & Zanden 1992
;
Rozen
et al.
2010
); exclusive pollen hosts are species of Hedysareae (e.g.
Hedysarum
,
Onobrychis
).
Nesting biology.
O. avosetta
nests in excavated,
3–7 cm
deep burrows in rather loose, sandy to gravelly ground usually containing one vertically oriented brood cell at the end of the burrow, rarely two cells immediately beside each other (
Fig. 17
;
Rozen
et al
. 2010
). The cells, which range in depth from
1.5–5 cm
and have a length of
15–17.5 mm
and a diameter of
7–9 mm
, are distinctly three-layered with a thin mud layer sandwiched between two layers of large petal pieces of
Hedysarum
,
Onobrychis
(both
Fabaceae
) or other plant taxa. Whether the short and
6–7 mm
wide entrance burrow leading to the brood cell(s) remains open after cell closure is unclear, but indications exist that the females do not actively fill it with soil or other particles.
Brood parasites
: probably
Sapyga pulcherrima
Morawitz (Sapygidae)
(
Rozen
et al
. 2010
).
