beetle is very similar to the Australian Spider Beetle
what makes this beetle stand out are the golden hairs which cover it's
back and head. It can feed on almost anything and when it appears in a
house the source of infestation could be dead chicks in a birds nest in
the roof space combined with a collection of seeds which were going to
be used next year. Now and again this beetle has been recorded as a pest
of textiles as you can see from the picture below:

addition to the usual wide variety of products that are generally attacked
by spider beetles, the adults and larvae of this species feed on woolens,
linens, and natural silks, particularly if the fabrics are soiled with
grease. The beetles are most commonly found in vegetable and animal debris
in warehouses, poorly kept storerooms, cellars, and old houses, and sometimes
occur in considerable numbers. They shun light, but move actively in the
dark. The nests of bees, wasps, and birds provide their natural habitats.
The adults are 3 to 4.5 mm long and golden yellow, with long, silky hairs
covering the fused elytra. Flight wings are absent.
Cycle: Oviposition and the appearance
of the eggs and larvae are similar to their equivalents in Ptinus
ocellus. The eggs hatch in 11 to 20 days at
64 to 68° F (18 to 20°C); the larval period lasts about 150 days; and
the pupal period, 18 to 26 days. The adults may live as long as 250 days.
