Porcellio dilatatus Brandt, 1833
This large species, reaching 15 mm, is rarely recorded. Not because it’s uncommon, but simply because recorders don’t look in the correct places. It is most commonly found in or around stables or cattle sheds, often within well-established manure heaps. Indeed, targeted surveys in Leicestershire have shown it to be common in dairy farm yards across the entire county. Sightings elsewhere are often from compost heaps in churchyards, gardens and allotments and inside glasshouses. Read BMIG's species account here.
