Ranging from dwarfs to giants, the species of honeybees show remarkable differences in body
size that have placed evolutionary constrains on the size of sensory organs and the brain. …

Orchids of the genus Ophrys are pollinated by males of solitary bees and wasps through sexual
deception. The flowers mimic the behaviourally active compounds of the sex pheromone …

Stingless bees constitute a species-rich tribe of tropical and subtropical eusocial Apidae
that act as important pollinators for flowering plants. Many foraging tasks rely on vision, eg …

In a recent research article in the Botanical Journal of the Linnean Society Bradshaw et al.(2010)
provided a detailed and richly illustrated comparative analysis of labellum …

Colour vision was first demonstrated with behavioural experiments in honeybees 100 years
ago. Since that time a wealth of quality physiological data has shown a highly conserved set …

Sexually dimorphic sensory systems are common in Hymenoptera and are considered to
result from sex‐specific selection pressures. An extreme example of sensory dimorphism is …

In the Mediterranean region, a group of unrelated plant species share an unusual deep-red
flower color and are pollinated by glaphyrid beetles. Some of these species possess …

We tested the endemic Australian Tetragonula carbonaria bee as a model of how colour
vision may allow these small bees to find flowers. In a Y-Maze apparatus, we presented stimuli …

Non-rewarding orchids rely on various ruses to attract their pollinators. One of the most
common is for them to resemble flowers sought by insects as food sources. This can range from …

The East Himalaya is one of the world’s most biodiverse ecosystems. However, very little is
known about the abundance and distribution of many plant and animal taxa in this region. …
