Rathke's Woodlouse

Fascinating facts about the Rathke's Woodlouse

• Rathke's woodlouse occupies almost the whole of the European continent, thriving in a wide range of temperate zones. It is completely absent from the Mediterranean Basin, where the climate is too dry for its moisture-loving habits. This distribution means the species can be encountered from the Atlantic coast to the eastern borders of Europe, filling many suitable habitats across the continent.
• The species has been introduced to North America and now spans the majority of the northern United States and southern Canada, establishing populations far from its native range. Records show it reaching as far west as the province of Alberta, demonstrating its ability to colonise diverse northern environments. Its presence across such a broad area reflects its tolerance of varied climatic conditions in the continent's cooler regions.
• The woodlouse's exoskeleton is a slate-grey colour adorned with three thin, pale longitudinal stripes that give it a distinctive striped appearance. Individuals grow to about 15 mm in length, a size that allows them to hide under stones, bark and leaf litter. Females sometimes display orange mottling on their backs, adding a subtle colour variation to the otherwise muted palette.
• It possesses five pairs of pleopodal lungs and two antennal flagellar segments. The woodlouse favours poorly drained, damp sites and can survive prolonged flooding, which makes riverside meadows and floodplains ideal habitats.
