Oncid ID is designed to aid in the identification of adult "twig girdlers," a large group of longhorned beetles in the tribe Onciderini which are widely distributed in the Nearctic and Neotropical regions, from the USA to Argentina. The tribe currently contains 79 genera and ~481 species.

Members of this group are known to attack more than 50 different woody plant families, including many economically and agriculturally important species such as avocado, cocoa, coffee, guava, grape, peach, pecan, and sweet potato. Within their native range, trees attacked by these beetles are often severely damaged or killed. The potential introduction of exotic twig girdler species into the USA poses a serious risk to our native trees.
