Collective behaviors are present across many different animal groups: schools of fish swimming in a swirling pattern together, large flocks of birds migrating through the night, groups of bees coordinating their behavior to defend their hive. These behaviors are commonly seen in social insects where as many as thousands of individuals work together, often with distinct roles. In honey bees, the role a bee plays in the colony changes as they age.

Honey bee workers collect pollen and nectar from a variety of flowering plants to use as a food source. Honey bees typically forage from up to 1-2 miles away from the hive, though sometimes they travel even further, including up to 10 miles away. However, much of the modern landscape consists of agricultural fields, which limits the foraging options for honey bees in these areas.

More than a decade after the identification of colony collapse disorder, a phenomenon marked by widespread loss of honey bee colonies, scientists are still working to untangle the ecologically complex problem of how to mitigate ongoing losses of honey bees and other pollinating species. One much-needed aid in this effort is more efficient ways to track specific impacts on bee health. To address this need, a group of Illinois researchers has established a laboratory-based method for tracking the fertility of honey bee queens.
