Long-jawed Longhorn Beetle
Dendrobias mandibularis is a species of longhorn beetle (Cerambycidae) described by Dupont in 1834. The species is notable for its enlarged mandibles, particularly in males. It has been collected in desert thorn-scrub habitats in Arizona and is associated with Baccharis sarothroides vegetation. The species exhibits sexual dimorphism in mandible development, with major males possessing substantially enlarged jaws.
