Ondatrinae

Ondatrinae is a subfamily of beetles in the family Cerambycidae. The subfamily is mostly found in temperate regions of the Northern Hemisphere, with distributions in North America, Europe, and Asia. Members of Ondatrinae are typically classified based on the presence or absence of distinctive structures, such as the shape of the mandibles and the formation of the pronotum.

One of the defining characteristics of the Ondatrinae subfamily is the nearly always biconcave elytral profile, although some species show some deviation from this. Oviposition takes place on or in plants of the Salicaceae, Ulmaceae, Betulaceae, and Fagaceae families, resulting in larvae that feed on sapwood and phloem. Beetles within this subfamily display a seasonally varying coloration pattern, which may be temporal or trans-meristic.

Research on Ondatrinae is often constricted within a limited geographical scope, and it generally targets descriptions of existing infra-species, especially those related to economic importance. Rarely are sub-genus-level revisions done.

Species in the Ondatrinae subfamily often exhibit unique visual adaptations, such as brighter colors during their initial venation sequences. This generally is taken into consideration when knowledge gaps exist about accurately indentifying the level of species variability.
