Biological observations and data on host timber species utilized by the Australian tenebrionid Achthosus westwoodi Pascoe, 1863 (Coleoptera: Tenebrionidae: Ulomini) are listed herein from the personal opportunistic observations of the author in various areas of eastern Australia from 1972-2008. The adults and larvae of A. westwoodi utilize a broad range of native and introduced timbers from several plant families, viz. Casuarinaceae (Casuarina), Fagaceae (Nothofagus), Myrtaceae (Eucalyptus), Mimosaceae (Acacia), Proteaceae (Banksia), Rhamnaceae (Alphitonia) and Bignoniaceae (Jacaranda).
