|Apocephalus borealis is a species of North American parasitoid phorid fly that parasitizes bumblebees, honey bees, and paper wasps. These flies are colloquially known as zombie flies and the bees they infect are known as zombees. Recently the fly has changed host and has begun to attack the European honey bee.|
First spotted on Vancouver Island, a first for Canada, experts believe they have reached the mainland. A phorid fly lays eggs inside a honeybee, and the fly larvae will eat away at the bee’s insides.
