    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...

    How Does Pollen Chemistry Impact Development and Feeding Behaviour of Polylectic Bees? Larvae and imagos of bees rely exclusively on floral rewards as a food source but host-plant range can vary greatly among bee species. While oligolectic species forage on pollen from a single family of host...

    Development of a New Method to Track Multiple Honey Bees with Complex Behaviors on a Flat Laboratory Arena A computer program that tracks animal behavior, thereby revealing various features and mechanisms of social animals, is a powerful tool in ethological research. Because honeybee colonies...

    Social Reinforcement Delays in Free-Flying Honey Bees (Apis mellifera L.) Due to the cyclical rhythm of honey bee foraging behaviors, a post-reinforcement delay at a foraging location would in turn delay a variety of social behaviors in the hive such as unloading behaviors. Free-flying honey...

    Observation and guesses. We have a single box hive with an empty box above to protect the feeding jar. Last night we noticed a behavior I have been unable to figure out. At each entrance to the hive about 10 worker bees are hanging out. Figuring it might be too hot or crowded Ruth and I...
