It is said the species seems to prefer well-vegetated and shaded areas on lowland chalk and limestone sites where it is associated with Beech and Birch.
All year round, but peak time seems to be May to September. All four VC55 records up to the end of 2014 were recorded in August or September.
Larvae develop in dead wood, feeding on micro-organisms in fluids, they may also be predatory.
Quite scarce, but widely distributed throughout England and Wales south of the Wash, scattered records from mid and north Yorkshire and absent from the west country and western Wales.
