Prioninae

Prioninae is a subfamily of longhorn beetles (family Cerambycidae). These beetles are characterized by their generally large size, flattened bodies, and prominent mandibles (jaws). They are often found in tropical and subtropical regions worldwide, although some species also occur in temperate zones.

Prioninae larvae typically bore into dead or decaying wood of various tree species, often playing an important role in decomposition. The larval stage can last for several years, during which they feed extensively. Adult Prioninae are often nocturnal and may be attracted to lights.

Distinguishing features of Prioninae beetles often include the presence of serrated antennae in males, although this characteristic varies among species. They are typically brown or black in color. The subfamily is diverse, containing a significant number of genera and species. The classification of Prioninae and its relationships to other Cerambycidae subfamilies has been subject to ongoing research and taxonomic revisions.
