Bumble-bee learning selects for both early and long flowering in food-deceptive plants

Bumble-bee learning selects for both early and long flowering in food-deceptive plants.

Most rewardless orchids engage in generalized food-deception, exhibiting floral traits typical of rewarding species and exploiting the instinctive foraging of pollinators. Generalized food-deceptive (GFD) orchids compete poorly with rewarding species for pollinator services, which may be overcome by flowering early in the growing season when relatively more pollinators are naive and fewer compe...

An Early Miocene bumble bee from northern Bohemia (Hymenoptera, Apidae)

A new species of fossil bumble bee (Apinae: Bombini) is described and figured from Early Miocene (Burdigalian) deposits of the Most Basin at the Bílina Mine, Czech Republic. Bombus trophoniussp. n., is placed within the subgenus Cullumanobombus Vogt and distinguished from the several species groups therein. The species is apparently most similar to the Nearctic B. (Cullumanobombus) rufocinctus ...

Changes in Learning and Foraging Behaviour within Developing Bumble Bee (Bombus terrestris) Colonies

Organisation in eusocial insect colonies emerges from the decisions and actions of its individual members. In turn, these decisions and actions are influenced by the individual's behaviour (or temperament). Although there is variation in the behaviour of individuals within a colony, we know surprisingly little about how (or indeed if) the types of behaviour present in a colony change over time....

Bumble Bee (Hymenoptera: Apidae) Foraging Distance and Colony Density Associated With a Late-Season Mass Flowering Crop

Foraging behaviors of bumble bee workers have been examined in natural habitats, whereas agricultural landscapes, which can provide insights on ßight distances to fragmented patches of bloom,have received limited attention. Inparticular, informationonworkerßightdistances to crops blooming several months after nests have been established is invaluable. Here, we examined foraging patterns of Bomb...
