Twig Girdler Oncideres spp. (Insecta: Coleoptera: Cerambycidae: Onciderini)

by Miranda Barnes and Jiri Hulcr

This Featured Creatures article discusses the habits, distribution, appearance, life history, ecology, and other features of twig girdlers in the genus Oncideres, with a particular focus on O. cingulata cingulata in Florida. It describes hallmarks of twig girdler damage and discusses the common hosts of different twig girder species. Authors Miranda Barns and Jiri Hulcr detail the life cycle and phenology of the insect, as well as theories about the purpose of its girdling behavior. The publication provides an overview of management practices for pecan growers, and reassures homeowners that the insect is not a serious threat to ornamental trees.
