Pollen hosts.
Probably polylectic with strong preference for
Fabaceae
(Tab. 1); pollen hosts among the
Fabaceae
are species of Hedysareae (e.g.
Onobrychis
) and other tribes. Additional plant families recorded in small quantities in the pollen loads analysed were
Brassicaceae
,
Papaveraceae
and
Asteraceae
(
Asteroideae
,
Cichorioideae
). The females of
O. agilis
possess long and apically curved bristles on the galeae of the proboscis. Such specialized bristles have evolved in several bee taxa for scraping pollen out of flowers which have their anthers concealed within narrow tubes (
Müller 1995
,
2006
;
Parker & Tepedino 1982
;
Thorp 1979
,
2000
). However, none of the pollen hosts recorded for
O. agilis
so far possesses narrow-tubed flowers, rendering the function of these specialized bristles enigmatic.
Nesting biology.
