Bumble bees are important pollinators of crops and other plants. However, many aspects of their basic biology remain relatively unexplored. For example, one important and unusual natural history feature in bumble bees is the massive size variation se

Complex systems (e.g. eusocial insect colonies) exhibit emergent behaviours as a result of the interactions of their components. These components often vary in several traits. Such variation may improve system performance by increasing its efficiency

Task specialization is one of the distinguishing features of social insect colony organization. Here we study the task of corpse removal (‘undertaking’) from the nest in three Bombus impatiens colonies. We determine (1) which task these bees perf

Phenotypic variation within biological systems is ubiquitous and often assumed to be adaptive in social insects. Local environmental factors, such as temperature, may affect the phenotypic variation produced, and yield insights into the mechanisms th

A host of animals build architectural constructions. Such constructions frequently vary with environmental and individual/colony conditions, and their architecture directly influences behavior and fitness. The nests of ant colonies drive and enable m

Although models of colony organization in social insects often rely on the assumption that within-group variation increases group performance, empirical support for this is mostly confined to studies of genetic variation. However, workers in ant or b

Colony size can affect individual- and colony-level behavioral and physiological traits in social insects. Changes in behavior and physiology in response to colony growth and development can affect productivity and fitness. Here, we used respirometry

Social insect colonies are highly successful, self-organized complex systems. Surprisingly however, most social insect colonies contain large numbers of highly inactive workers. Although this may seem inefficient, it may be that inactive workers actu

Social insects are distinguished by their extraordinary degree of cooperation and the complexity of their group organization. However, a high proportion of individuals (often .50% at any one time) in a social insect colony tend to be inactive. It has
