The white-marked spider beetle appears in the same type of products as the Australian spider beetle, that is, in dry organic substances. It is not as common as the Australian spider beetle in storages, but it is common in nature. Males are elongated, with almost parallel sides, while the female has round arched elytrons. On the prothorax, it has two stripes of closely spaced white-yellow hair, which comes together in the back and draws a V. On the elytrons there are 4 white-yellow spots.

Nowadays this European beetle is not as common as the Australian species just described. It eats the same kinds of food, including offal, but it is never a serious pest, partly because the female lays only about 50 eggs. This beetle is found both indoors and out in the open in Britain.
