Ptinus sexpunctatus in British Entomology

Description

The species is approximately 4–5 mm in length and is a uniform dark olouration. It has very prominent basal and apical patches of appressed white scale. The grooves on the elytra are very deep. [2]

Distribution

Ptinus sexpunctatus is a Palearctic spider beetle (Anobiidae: Ptininae) found throughout Europe.[1] It was recently recorded in North America, in 2007.[1]

Habitat

The six-spotted spider beetle has been associated with pine forests generally,[3] although more cosmopolitan sightings have occurred indoors.[4][5] The beetle also parasitises the nests of cavity-nesting solitary bees in the genera Osmia and Megachile.[1] One example has been recorded, from Nova Scotia, Canada, in the nest of the Blue Orchid Mason Bee (Osmia lignaria).[2]

In the United Kingdom it is categorised as 'Nationally Notable B' by the National Biodiversity Network.[6]
