Description 1

Large isopod (up to 18 mm in length). Oval shaped, with a fairly flat bib and body twice as long as it is wide. They are a dull grey colour (chalkboard grey), and sometimes have brown or red pigmentations. Wide scutellum that does not go above the head. Two pairs of antennae (one can almost not be seen), a thorax with 7 visible segments and seven pairs of legs.

Biology 1

They have a life cycle of approximately 3 years. If the bioclimatic conditions are good, they can have up to two generations a year. They have a reproductive peak in the spring and a second, less important one during the autumn. A large omnivorous species. They mainly feed on rotting plant matter.

Habitat 1

Coastal areas, agricultural terrain and anthropic green areas, areas of xerophyte bushland of the altitudinal zonation, bushlands in mountainous environments, and peaks, forests, humid mountain forests, grassland and pastures in altered environments, partially underground and even urban environments. In laurisilva forests they mainly inhabit the areas that have more light, and have a lesser density further inside the forest.
