Orchid bee collects herbicide that mimics the fragrance of its orchid mutualists

Florida Entomologist
Abstract Male orchid bees store volatile compounds collected from their orchid mutualists and other sources to use in their courtship. Males of a naturalized orchid bee in Florida, Euglossa dilemma Bembé & Eltz (Hymenoptera: Apidae), intensively and habitually collected from substrates impregnated with triclopyr herbicide, most ...

Carry-over effects of bumblebee associative learning in changing plant communities leads to increased costs of foraging [PDF]

, 2018
Flower visitors learn to avoid food-deceptive plants and to prefer rewarding ones by associating floral cues to rewards. As co-occurring plant species have different phenologies, cue-reward associations vary over time.

Pollinator-attracting semiochemicals of the wasp-flower Epipactis helleborine [PDF]

, 2008
The orchid genus Epipactis is represented by 25 species in Europe (Richards 1982). Epipactis helleborine (L.) Crantz is the most common and widely distributed species of the genus (Wiefelspütz 1970), and is a prime example for wasp-flowers, because it is

Colour reverse learning and animal personalities: the advantage of behavioural diversity assessed with agent-based simulations [PDF]

, 2012
Foraging bees use colour cues to help identify rewarding from unrewarding flowers, but as conditions change, bees may require behavioural flexibility to reverse their learnt preferences.

Interaction networks and the use of floral resources by male orchid bees (Hymenoptera: Apidae: Euglossini) in a primary rain forests of the Chocó Region (Colombia)

Revista de Biología Tropical, 2015
Orchid bees are important keystone pollinators from the Neotropics. With the aim to study the relationships between orchid bees and their nectar and aromatic host species, we made systematic samplings of males across two conservation areas in the ...
