Cylindroiulus punctatus
(Leach, 1816)
blunt-tailed snake millipede
Cylindroiulus punctatus, commonly called the blunt-tailed snake , is a widespread European millipede in the Julidae. It is the most commonly recorded millipede in Britain and Ireland, strongly associated with woodland where it feeds on decaying wood and leaf litter. The exhibits seasonal vertical , in soil and moving to litter and logs during warmer months, with individuals sometimes found metres above ground in trees during summer. It takes three years to reach sexual maturity and can live for several additional breeding years. The species has been introduced to Newfoundland and Nova Scotia in North America.

Habitat
Strongly associated with woodland , particularly dead and decaying wood and under the bark of dead trees. Occupies both decaying logs and soil, with seasonal movement between these microhabitats. Found in non-calcareous, commonly loamy soils. Shows negative association with , sand dunes, and grassland. In the British Isles, has a rural and semi-natural distribution.
Distribution
Native to western Europe, ranging from southern Scandinavia and the Shetland Islands to northern Spain and the Balearic Islands. Most commonly recorded in Britain and Ireland, found in nearly all parts of both islands. Generally a thermophilic lowland , though occur above 1000 m in northeastern Spain. Introduced to Newfoundland and Nova Scotia, Canada.
Seasonality
Seasonal vertical pattern: in soil, shifting to litter and logs during warmer months. By spring, individuals move into trees and may be found metres above ground during summer months.
Diet
Feeds on wood and leaf litter.
Life Cycle
Reaches sexual maturity at stadium VIII during the third winter. Females can breed for several additional years, reaching a maximum of 14 stadia. Mating and -laying occur during warmer months. Nests are constructed beneath the bark of fallen logs and stumps, found from May to August. Batches contain 45 to 60 eggs.
Behavior
Exhibits seasonal vertical between soil (winter) and litter/logs/trees (warmer months). and later stages display a club-shaped caudal projection.
Ecological Role
Decomposer in woodland , processing wood and leaf litter.
