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
Nationally much less frequent than in the days of horse drawn vehicles, when manure heaps were common everywhere. However, recent searches indicate that it may be widespread, even numerous, in and around farms and riding stables, as far north as the Highlands.
100 years ago this was undoubtedly a common insect throughout Cornwall. In the last 25 years there have been just three Cornish records. It is probably much under-recorded, as few would wish to delve deeply into dung heaps! The most recent record was at St. Wenn, where there was a very active colony in a damaged compost bin; a more genteel habitat for the squeamish to investigate.
Habitat & Ecology
Found in manure heaps and compost bins. The adults fly freely in hot weather, by day and night, and this tiny earwig (little larger than an ant) has been attracted to the MV lights of moth recorders.
Excessive farm hygiene.
