Lyctidae
A small (of about 70 species) family of beetles whose larvae bore in and feed on wood. Their common name, powder post beetles, refers to the ability of the larvae to reduce dry wood or lumber to powder. The adults, which do not feed, are small, dark brown, about 10-15 mm in length, with striated elytra. The larvae are slightly curved, up to 5 mm in length, yellowish-white, with large spiracles on the posterior of the abdomen. Development of a generation usually takes about one year. If wood conditions are right, emerging females may oviposit in the same wood and thus re-infest it, continuing the cycle for generations. Their economic importance is due to being major pests of wood products, and to sometimes being destructive to deciduous fruit trees. Wood preservatives can be used to prevent infestations.
