Range
Widespread
North and south temperate zones around the world; widespread in NA and ranges farther north (into BC & PQ) than any other earwig (1). Native to NA, according to ITIS, but compare the opinion of M.S. Engel: "L. minor is very likely an established adventive species. However, records to document this are very poor and, if truly introduced, then it became established and widespread a very long time ago. The first record I know of for L. minor in the United States is from around 1838, but it was likely already here for some time prior to that. Given its ubiquity and long history in the Nearctic (and other areas of the world), it is now effectively 'native' everywhere." (pers. comm. to =v= 5/21/10)
Habitat
Around manure and on flowers; often numerous under debris and manure taken in flight or at lights (1)(3)
Food
Manure maggots(1), decaying plant material
Remarks
Uses its forceps to comb out the wings(1) (video)
NB: searching for "Labia minor" is possibly NSFO (not safe for office), so add the word 'Dermaptera' to your search...
