Arianta arbustorum, sometimes known as the copse snail, is a medium-sized species of pulmonate land snail in the family Helicidae.[3]

Subspecies

Arianta arbustorum alpicola

Several subspecies are recognized by some authors:

  • Arianta arbustorum alpicola Férussac, 1821
  • Arianta arbustorum arbustorum (Linnaeus, 1758)
  • Arianta arbustorum canigonensis (Boubée, 1833)
  • Arianta arbustorum picea
  • Arianta arbustorum pseudorudis (Schlesch, 1924)
  • Arianta arbustorum repellini (Reeve, 1852)
  • Arianta arbustorum styriaca (Frauenfeld, 1868)
  • Arianta arbustorum vareliensis Ripken & Falkner, 2000

Distribution

This species is native to Europe:

  • North-western and central Europe with Alps and Carpathians[4]
  • Netherlands[5]
  • Austria
  • Czech Republic
  • Slovakia
  • Poland
  • Switzerland. One of the most frequent species of land snails in Switzerland, can be very abundant, up to 20 adults per square meter.[4]
  • eastern Pyrenees, Spain[4]
  • Norway[4]
  • Iceland[4]
  • Faroe Islands[6]
  • the British Isles: Great Britain and Ireland[4] In Britain the species suffered slightly from intensive farming and the continuous destructions of suitable uncultivated refuges.[4] It is rare in Ireland.[4]
  • Kaliningrad[4]
  • Finland. In Finland, it has become so common in the Porvoo region east of Helsinki, that it is locally called the "Porvoo snail".
  • Estonia[4]
  • Latvia[4]
  • scattered to Serbia[4]
  • Bulgaria[4] It is rare in Bulgaria.[4]
  • western Ukraine[4]

Arianta arbustorum is introduced to North America, but is only known from Canada, where established populations are known from Newfoundland, New Brunswick, Ontario,[7] and Prince Edward Island.[8]

This species has not yet become established in the US, but it is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. Therefore, it has been suggested that this species be given top national quarantine significance in the USA.[9]

Description

The shell is usually brown with numerous pale yellowish rows of spots and usually with a brown band above the periphery, occasionally yellowish, reddish or with greenish hue, weakly striated and with fine spiral lines on the upper side.[4] The shell has 5-5.5 convex whorls with deep suture.[4] The last whorl is slightly descending near the aperture.[4] The aperture is with prominent white lip inside.[4] The apertural margin is reflected.[4] Umbilicus is entirely covered by the reflected columellar margin.[4]

The width of the shell is 18–25 mm.[4] The height of the shell is 12–22 mm.[4] Dimensions are locally variable.[4]

The shell shape is globular in most present-day populations, but originally is believed to have been depressed in the Pleistocene, before lowlands were invaded and shells became globular, re-invading mountain regions except some isolated spots among glaciers.[4]

The animal is usually black.[4]

Life cycle

Arianta arbustorum lives in forests and open habitats of any kind.[4] It requires humidity.[4] It lives also in disturbed habitats (not in Ireland where it is restricted to old native woodland).[4] It may locally tolerate non-calcareous substrate, in north Scotland also on sandhills.[4] In the Alps up to 2700 m, in Britain 1200 m, in Bulgaria 1500 m.[4]

It feeds on green herbs, dead animals and faeces.[4]

If snails hatched more than 50 m distant from each other, they are considered isolated since they would not move more than 25 m (neighbourhood area 32–50 m), usually they move about 7–12 m in a year, mostly along water currents.[4]

This species of snail makes and uses calcareous love darts during mating. Reproduction is usually after copulation, but self-fertilization is also possible.[4] The size of the egg is 3.2 mm.[10] Maturity is reached after 2–4 years.[4] The maximum age up to 14 years.[4]

Angiostrongylus vasorum has successfully experimentally infected this snail.[11]

Prevention

Metaldehyde and iron phosphate can be used to exterminate snails.[12] Since copper generates electric shocks that make it difficult for snails to move, it makes a great barrier material for them.[13]
