Bombardier Beetle - Brachinus fulminatus - female

Bombardier Beetle - Brachinus fulminatus - Female
Groton, Middlesex County, Massachusetts, USA
May 10, 2009
Size: 8.7mm

Moved from Bombardier Beetle.

Brachinus fulminatus - female
based on my microscopic examination of this specimen including dissection and study of female gonostyle. Thanks Tom.

why female
Why female? any dissection proof?

because I had the advantage of actually seeing the tiny dissected female genitalia as part of my examination of this specimen. But the image tells you it's a female based on the rather narrow protarsi (= distal segments of foreleg) which are much more dilated in males.
