Introduction:
Anobiids generally possess a wide, hood-like prothorax into which the strongly deflexed head is withdrawn; two adventive European species are specifically referred to as the ‘death watch beetles’ due to conspicuous tapping within infested structural timbers. The long, filiform antennae and swollen pterothorax/abdomen of species within the subfamily Ptininae have resulted in the common name, ‘spider beetles’.

Adult Diagnosis:
head strongly deflexed antennae usually 11-segmented with terminal three segments highly modified (elongate, serrate, etc. - especially in males) pronotum generally wider than head, hood-like, often concealing head entirely from dorsal view legs generally short metathoracic trochanters cylindrical

Ecology:
Anobiidae represent a diverse family, found in a wide variety of habitats; the larvae of many species bore into fungi and a variety of woody materials including structural lumber. Some species, such as the death watch beetles, Anobium punctatum (DeGeer) and Xestobium rufovillosum (DeGeer), are responsible for significant damage to furniture and lumber; other species are economically significant in stored products. Spider beetles (Ptininae) range from wood borers to consumers of dried animal and plant materials, to bee commensals
