Bombardier Beetle - Brachinus cyanipennis

Bombardier Beetle - Brachinus cyanipennis
Groton, Middlesex County, Massachusetts, USA
June 20, 2012
Size: 8.6mm

Moved from Bombardier Beetle.
Thanks Peter.

Brachinus cyanipennis
based on my microscopic examination of this specimen** which is now a photo-voucher in the P.W.Messer collection. Thanks Tom.

** I encountered difficulty in associating images to identified specimens of which 5 similar Brachinus were bunched in same collection container. The only Brachinus in the bunch with the first three basal antennomeres pale (as in image) was B. cyanipennis. I measured body length (not including abdomen) to be ~ 9 mm.
