The evolution of floral traits in animal-pollinated plants involves the interaction between
flowers as signal senders and pollinators as signal receivers. Flower colors are very diverse …

Iridescence, the change in hue of a surface with varying observation angles, is used by
insects, birds, fish, and reptiles for species recognition and mate selection. We identified …

Bee pollination is economically and ecologically vital and recent declines in bee populations
are therefore a concern. One possible cause of bee declines is pesticide use. Bumblebees …

Insects possess miniature brains but exhibit a sophisticated behavioral repertoire. Recent
studies have reported the existence of unsuspected cognitive capabilities in various insect …

Flowering plants in Australia have been geographically isolated for more than 34 million
years. In the Northern Hemisphere, previous work has revealed a close fit between the …

The visual ecology of flies is outstanding among insects due to a combination of specific
attributes. Flies' compound eyes possess an open rhabdom and thus separate rhabdomeres …

Bumblebee (Bombus terrestris) discrimination of targets with broadband reflectance spectra
was tested using simultaneous viewing conditions, enabling an accurate determination of …

Neonicotinoids are widely-used pesticides implicated in the decline of bees, known to have
sub-lethal effects on bees' foraging and colony performance. One proposed mechanism for …

We studied the influence of the conditioning procedure on color discrimination by free-flying
honeybees. We asked whether absolute and differential conditioning result in different …

Visual learning admits different levels of complexity, from the formation of a simple
associative link between a visual stimulus and its outcome, to more sophisticated …
