<DIV>David sent me the below. It is likely hbs are also repelled by the scent
of Anthidium.</DIV>

</X-TAB>Honeybees and bumblebees avoid probing flowers that have been
recently depleted by conspecifics, presumably repelled by odours deposited
by the previous visitor (foraging scent marks). Here we show that females
of the solitary wool-carder bee Anthidium manicatum (Megachilidae)
discriminate against previously visited inflorescences (Stachys
officinalis), and that discrimination is equally strong regardless of
whether the previous visitor is conspecific or belongs to a different bee
family (Bombus terrestris, Apidae). Conversely, workers of B. terrestris
responded differentially to different previous visitors, with previous
visits by A. manicatum eliciting the most pronounced repellent effect.
This finding may have resulted from the bumblebees' avoidance of impending
aggression by territorial A. manicatum males. Our results emphasize that
foraging scent mark recognition is not necessarily linked to sociality,
but a trait of individuals foraging in an unpredictable flower visitor
community.</BLOCKQUOTE></BLOCKQUOTE>
