AppearanceThis beetle is bright green-blue and red-brown in color. The adults are 5.6–7.7 mm long, with females larger than males.
BehaviorThis beetle forms aggregations of several individuals, often with beetles of the genus ''Brachinus''. When disturbed it releases a volatile that contains undecane. Its coloration may be aposematic mimicry of the similarly colored ''Brachinus'' beetles it lives with, which emit a much more powerful antipredator volatile mix.
