Brachydesmus superus, sometimes called the flat millipede,[2][3] is a species of millipede in the family Polydesmidae.[4][5] Its specific name is from the Latin word for "above, upper,"[6] because it lives in the upper soil layer.[7]

Appearance

[edit]

A light brown or grey flat-backed millipede. Adults are up to 1 cm (0.39 in) long, with 19 segments (including the telson), unlike most other adults in the family Polydesmidae, which usually have 20 segments.[8] Accordingly, adults in this genus have two fewer legs than most polydesmid adults have: Females have only 29 pairs of legs, and males have only 28 pairs of walking legs, excluding one pair of gonopods.[9][10]

Distribution

[edit]

Native to Europe, also found in New England.[11]

Behaviour

[edit]

Lives in damp terrestrial habitats.[12] Female lays about 50 eggs in spring or summer in a dome-shaped nest. The first-staged larva has seven segments and three pairs of legs; it moults six times (sometimes seven for males) before reaching adult size.[13]

They are known as a pest in sugar beet fields.[14]
