# Greenhouse millipede

The greenhouse millipede (Oxidus gracilis), also known as the hothouse millipede, short-flange millipede, or garden millipede, is a species of millipede in the family Paradoxosomatidae that has been widely introduced around the world, and is sometimes a pest in greenhouses.

## Description

Greenhouse millipedes achieve lengths of 18 to 23 mm (0.71 to 0.91 in) as adults, and widths from 2 to 2.5 mm (0.079 to 0.098 in). The dorsal section of each segment has a transverse groove, a trait found in most paradoxosomatids. They are brown in color with pale cream-colored legs and paranota (lateral "keels" extending from each segment).

## Distribution

Greenhouse millipedes are thought to be native to Japan, but have been introduced globally. They are found in the tropics as well as temperate North and South America, North of Iran, and all of Europe.
