Wanted: leaf litter samples from anywhere in Canada
While the minute land molluscs that dwell in leaf litter are a major component of the terrestrial mollusc fauna of Canada, they have historically been neglected in many parts of Canada. Their small size has usually meant that they have been overlooked by all but the most dedicated naturalists and malacologists. Many gaps in our knowledge of these animals is the direct result of insufficient collections from almost all regions of the country. I am looking for donations of leaf litter samples (each 1–2 L in volume), or drift samples containing terrestrial species from anywhere in Canada. More information here.

Interactive maps at E-Fauna BC
October 2011 — New and updated data have been uploaded to E-Fauna BC, the Electronic Atlas of the Wildlife of British Columbia. Records are now available for terrestrial gastropods.

Need a mollusc identified?
Do you require identifications made of land snails or slugs? I can do these from specimens, or often from photographs. Please contact me for more information. I frequently help photographers, naturalists and others identify slugs and snails in their photos — just ask! Contact me here.

Oxychilus draparnaudi, Ottawa, 2016.

The somewhat unimaginatively named Dark-bodied Glass-snail — “Inky Blue Glass-snail” might have been better — is one of three species of terrestrial snail belonging to the genus Oxychilus in Canada. (Oxychilus alliarius and O. cellarius are the others.) Among these three species, this one is perhaps the most widely distributed, having been reported from Atlantic and Central Canada, as well as British Columbia. Many unpublished records exist in collections.

This photo was taken in an urban “wasteland” ravine in Ottawa in 2016.

Previous photos of this species are here  and here.
