Who needs horror movies when nature is right outside your door? The Zombie Fly is a parasite that preys on honey bees in California and a few other areas of North America. Affected bees appear to display “zombie-like behaviour”, causing them to leave their hives at night. The ZomBee citizen science project was initiated in order to better understand this bizarre phenomenon. It’s sponsored by the San Francisco State University Department of Biology, the San Francisco State University Center for Computing for Life Sciences, and the Natural History Museum of Los Angeles County. Partnered with Planet Bee Foundation, the goal of the project is to collect bees and observe them for zombie behaviour. To test for the presence of Zombie Fly infection all you need to do is put strangely-behaving honey bees which you collect in a container and observe them periodically. Infected honey bees produce brown pill-like fly pupae in about a week, which grow into adult flies a few weeks later. Once you’ve collected your data, upload it to an online map and see where other ZomBee citizen scientists have found infected bees as well.
