The P. testaceus imago is typically 6–16 mm in length. Their eggs are 1 mm long, and in athwart 0.5 mm. Larvae of the species are 10–18 mm long and 2.1 mm wide. Pupa are 9 mm long, and the abdomen is 2.8 mm wide.[3]

Distribution of these beetle extends from the European Atlantic coastline to the Southern Ural Mountains, from southern Sweden and Norway to North Africa and Syria.[3] It is also distributed throughout Japan and North America.[3]

Larvae develop in and under the bark of various deciduous tree species, causing damage. Larvae pupate in the spring. The beetle's life cycle lasts one year in central and southern parts, and two years in northern climes.[4]
