Klimaszewski, J., V. Assing, C.G. Majka, G. Pelletier, R.P. Webster & D. Langor. 2007. Records of adventive aleocharine beetles found in Canada (Coleoptera, Staphylinidae, Aleocharinae). Canadian Entomologist 139: 54-79.

 

Note: The Palaearctic biogeographic region includes Europe, the northwest coast of Africa, and Asia north of the Himalayan Mountains. This paper presents new reports of five Palaearctic species in Canada and compiles information on all the species of adventive aleocharines reported in the country. One of these, Crataraea suturalis, is newly recorded from Sable Island—this record is based on a single specimen (male) collected by H.F. Howden in 1967. The island’s invertebrate fauna includes a large suite of adventive insects. Forty-five of the 148 Coleoptera (beetle) species found on Sable are of Palaearctic origin. European contact with Sable Island, and introduction of domestic animals (cattle, pigs etc), began in the 1500s. Introductions, deliberate and accidental, continued through to the mid-1900s. Consequently many synanthropic beetles have been introduced (synanthropic species are those associated with humans and human dwellings). It is possible that C. suturalis was introduced to Sable directly from Europe because, thus far, this species has not been found elsewhere in Atlantic Canada. The principal habitats for this beetle are decaying organic material such as horse dung and decomposing organisms (e.g. corpses of horses, birds and seals) all of which are abundant on Sable Island.
