The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Range & Status

Formerly widely distributed in England but has become increasingly scarce in recent years and only reported from the south.

Regional Distribution

Two old records from Cornwall: the valley of Lynher (Clark, 1906) and a flour mill at St. Anthony in 1938 (R.T. Bannister). Discovered in large numbers on powdery

fungus inside an old hollow Beech Fagus sylvatica stump in Boconnoc Deer Park in 1989 (Alexander, 1991b).

Habitat & Ecology

A species of old pasture-woodlands, breeding in wood-decaying fungi; also occurring in granaries, food-stores etc. on decaying stored products.


Loss of the older age classes of trees, and removal of their associated deadwood.


Boconnoc Park has a sympathetic owner and is a SSSI.
