Life cycle

''Stylops'' larvae emerge from their host bee while the host gathers pollen from flowers. The larvae then attach to other bees in order to be carried back to the nest. At the nest, the ''Stylops'' larvae enter the bodies of bee larvae and develop along with their host. Adult males leave their hosts to mate with females, who remain inside their host and hatch their eggs there.
