Krynickillus melanocephalus

Krynickillus melanocephalus is a species of air-breathing

mollusc in the family Agriolimacidae.[2]
It is an invasive species, spreading from regions around the Black Sea to Northern and Central Europe.

Identification

The species resembles in form other agriolimacid slugs (notably

congener Krynickillus urbanskii (Wiktor, 1971), occurring in Romania, Bulgaria and Turkey, has a paler black head and a pale nape.[3][4]

Distribution

The natural range of Krynickillus melanocephalus is the Caucasus, Crimea, eastern Turkey and northern Iran.[5][6] It has been introduced more widely within Europe: further parts of Ukraine (e.g. Kyiv),[7] further parts of Russia (Moscow, Novgorod and Tverskaya oblasts),[8] Germany (since 1994),[9] Latvia (since 1997),[10][11] Belarus (since 2009),[12] Sweden (since 2015),[6] Lithuania (since 2017),[13] Finland (since 2017),[6] Hungary (since 2019),[4] Slovakia (since 2020),[14] Poland (since 2022),[15] and Estonia.[6]

Ecology

In its introduced range the species becomes adult in autumn and dies off in winter. It has spread from gardens to adjacent habitats, including woodland and meadows. Although it has sometimes been reported as a pest of crops, others have suggested that a diet of algae, fallen fruit, and fungi makes it less of a threat.[6] In its native range this is a forest species.[3] In experiments, slugs laid far more eggs in leaf litter than in moss, soil or gravel.[16]
