Bielzia coerulans, commonly known as the Carpathian blue slug or simply the blue slug, is a species of very large land slug, a terrestrial pulmonate gastropod in the family Limacidae, the keelback slugs.

Taxonomy

Bielzia coerulans was discovered in 1847 and described under the name Limax coerulans by Austrian-Hungarian malacologist, Michael Bielz (1787-1866), in 1851. (His son Eduard Albert Bielz was also a malacologist.)

Bielzia coerulans is the only species in the genus Bielzia.[1]

Some authors, for example Russian malacologists,[2] classify genus Bielzia as the only genus (monotypic) within the separate family, Limacopsidae.[2][3] There is also a separate subfamily, Bielziinae, for genus Bielzia (I. M. Likharev & Wiktor, 1980).

According to the taxonomy of Bouchet & Rocroi (2005), Limacopsidae and Bielziinae are synonyms for Limacinae.[4]

Description

This slug turns blue when an adult and becomes 100 – 140 mm in length.[9] It is evenly blue or bluish green (occasionally black) with a dark greyish head and tentacles, and margins pale yellowish, sole pale yellowish or whitish.[9]

Juveniles are yellowish brown with dark lateral bands.[9]

Reproductive system: Genitalia are without penis.[9] There is only an accessory organ for copulation.[9]

Ecology

Bielzia coerulans inhabits deciduous and coniferous forests in mountains, usually at the bottom, or under dead wood logs.[9]

Maturity is in June to July.[9] Copulation occurs at the soil.[9] There are 30-80 eggs laid in one clutch.[9] Adults die after egg deposition.[9] Half grown juveniles hibernate.[9] Fully grown slugs appear in May.[9]
