Grove Snails Caught Mating on a Garden Stone in Hervanta

Two grove snails were photographed mating on a garden stone in Hervanta recently. The images were published in Aamulehti.

Tomi Kumpulainen, curator at the Tampere Natural History Museum and the expert behind the Moro nature column, identified the animals as grove snails and noted they are simultaneous hermaphrodites: each individual functions as both male and female and exchanges gametes during mating. Many snail species can self-fertilize, but they usually prefer to pair.

Mating is slow and tactile. The snails probe with their tentacles before joining reproductive organs on the right side of the head, often out of sight. These encounters usually happen on moist days in spring or early summer, though they can occur later in the season as well.

The reader-supplied photo helped with identification, and the column continues to invite public observations accompanied by images.

The sighting follows other recent local reports, such as a leaf-snail sighting in Hämeenkyrö that prompted guidance from the Tampere Natural History Museum.
