Cerambycidae

Overview

Adult cerambycids are active fliers and may be diurnal or nocturnal; many feed on flowers, foliage or bark, and some are attracted to sugar baits. Larvae are phytophagous and usually feed internally on bark, phloem, sapwood or heartwood of a variety of trees and shrubs. Some species attack herbs, others are root feeders or gall formers, and a few may feed on seeds or cones.

Description

Elongate, subcylindrical to somewhat flattened beetles, usually pubescent; antennae almost always more than two-thirds body length and inserted on prominences, so that they can be directed backwards over the body. Eyes usually emarginate, often deeply so; lateral pronotal carinae absent, except in Parandrinae and Prioninae, often with lateral tubercles or spines on prothorax; mesonotum usually with stridulatory file; tibial spurs present on all legs; tarsal claws simple.

Larvae elongate, subcylindrical to slightly flattened, lightly sclerotised and subglabrous or clothed with fine setae or patches of spinules. Head retracted into prothorax and excavated posteriorly, forming a recess housing retractor muscle; antennae short; mandibles large and stout; prothorax usually more or less enlarged; legs small and widely separated and may be vestigial or absent; first 6 or 7 abdominal segments may bear fleshy ampullae which aid locomotion within wood; urogomphi, if present, minute.
