Although the primary function of hydrocarbons in the lipid layer of the cuticle is to prevent desiccation by hindering transpiration through the cuticle, there is a growing body of evidence that pheromones in the wax layer of the insect cuticle may mediate mate recognition in cerambycids. We identified cuticular hydrocarbons of cerambycid species of several subfamilies using Solid-Phase Microextraction and whole body hexane extraction with Gas Chromatography--Mass Spectrometry. We analyzed patterns in the structure and relative abundance of hydrocarbon components to determine whether hydrocarbon profiles show taxonomic patterns that may be exploited in studying the phylogenetic relationships among cerambycid species.
