Say hello to this Brachinus bombardier beetle from Arizona. So-named because it creates a hot, aimable explosion out of its butt when disturbed. I did not disturb it.

Is there a protocol for determining if you have a newly discovered species? How does one even get this confirmed. I'm referring to groups that are very speciose, like insects. #insects #entomology #biology

Or, if you prefer it as part of a family set, here's the same ant with her mom, and with a minor worker sister.

Top-down macro photograph of three blocky, black ants on a white background. All the ants are covered in evenly-spaced, silvery hairs, giving a glittery appearance. The ants at left and center have large, plate-like heads, the one at center, the queen, is quite elongated.

One of my favorite ants, the Texas turtle ant Cephalotes texanus. Photo is a live stack of three images, to improve depth of field.

#Ants#Cephalotes#Insects#TurtleAnt

Top-down macro image in portrait orientation of an inpressively angular tank of an ant with broad, sharp shoulders and ahead that looks like a fancy helmet with retractable antennae. The ant is mostly black, but is covered in glittering fine silver hairs over its entire body.

Ant fight!

Pavement ants (Tetramorium immigrans) pin down a worker from a rival colony. These suprisingly non-lethal battles are common as colonies expand their territories in the spring and summer. Indiana Dunes National Park.

Macro photograph in side view of four small dark brown ants surrounding a fifth ant of the same species, holding her by the mandibles, legs, and waist.
