Pezomyia speyeri Barnes, 1926
Holarctic, introduced in some parts of its range.
Paedogenesis is the normal reproductive method, with winged adults produced under crowded conditions.
A pest of cultivated mushrooms.
"It was first identified from Great Britain. It is now known from Europe, China and Japan. In the US its distribution is from Michigan, Pennsylvania, Maryland to Virginia. The larvae attack cultivated mushrooms and through shipping and world trade this species has been accidentally introduced to many ports of entry. Because the larvae cause economic damage to the mushroom industry, there is a great deal of literature surrounding this species."
