[1] [2] It affects members of the Prunus genus such as; cherry, plum, apricot, and chokecherry trees in North America.

Adult Dermestidae are generally small beetles (1–12 mm long), rounded to oval in shape, with hairy or scaly elytra that may form distinctive and colourful patterns. [3] [4] Except in genera Dermestes and Trichelodes, there is a single ocellus in the middle of the head.
The black carpet beetle (Attagenus unicolor) is a 3–5-millimetre-long (0.12–0.20 in) beetle that can be a serious household pest. The larvae grow to 7 mm (0.28 in) in length, are reddish brown in colour and covered with bristles. The larval form feeds on natural fibres, damaging carpets, furniture and clothing.
It is also called black patch disease. The infection is first seen as small black patches on the leaves of red clover (often on the bottom of the leaves first) and spreads to cover the entire plant, killing it. The hyphae of this fungus are white and web-like in appearance, just like those of other fungi.
