 CHCs are waxy chemical compounds that are found on the exoskeleton of most terrestrial arthropods that protect against desiccation, and these compounds have been found to be sexually dimorphic in "Teleogryllus oceanicus".It is thought that crickets use the information found in the CHC chemical signal to determine genetic similarity.In other words, crickets can sense how closely related an adjacent individual is by processing the odor exhibited by the CHCs.
