Entomophthora muscae

Description

This is a pathogenic fungus which causes a fatal disease in flies.

Identification difficulty
Habitat

This fungus may affect a number of different species of fly.

When to see it

Outbreaks of infection with Entomophthora muscae tend to occur in the spring and autumn.

Life History

Once infected the fly dies in about five to seven days. When it is critically ill, it tends to crawl to a high point, straighten its hind legs and open its wings, a behaviour that ensures that the fungal spores are dispersed as widely as possible. Some three hours later, conidiophores start to develop and a new shower of conidia is initiated.
