Androniscus roseus sensu auct. Brit. not C.L.Koch, 1837
Androniscus weberi Verhoeff, 1908
GB IUCN status: Least Concern
Although variable in colour, in life it is usually bright orange or salmon pink, but body pigment is rapidly lost in alcohol. The entire body is covered in coarse tubercles, easily seen with a hand lens, and the eye is composed of a single black ommatidium. As with all trichoniscid woodlice the antennal fagellum comprises a tapered cone (of indistinct segments) bearing a terminal bristle.
Distribution and Habitat
A common woodlouse across much of lowland Britain and Ireland.
It is equally at home in semi-natural coastal habitats, such as sparsely vegetated shingle, boulder beaches or erosion banks, and synanthropic sites including churchyards, gardens, waste ground, farmyards, etc.
It can be found in a wide array of microsites, but often on the underside of large stones or amongst rubble.
