Biology: Cluster fly are common through out Great Britain,
often hibernating in roof voids during the winter months. The adult flies emerge during March / April to lay
their eggs in silage, dung or grassland. The eggs hatch to produce larvae which are parasites of the earthworm,
feeding upon their host until they pupate. When the young adult emerges in autumn, it flies back to the same
hibernation space used by it's parents. During hibernation and emergence in spring, these flies can be seen
in the 10's of thousands.
This species of fly feeds on decaying vegetation and earthworms, they do not contaminate food stuffs,
and are not considered to be vectors of disease - they offer no risk to health. The main reason for control
is the association between flies and disease, and the discomfort the large numbers of these flies cause.
