Scientific Name: Calosoma argentinensis
Vulgar Name: Catanga or Juanita.

These beetles are the Carabidae family and are native to Argentina.

They are large beetles black with glitter, metallic and iridescent. They have glands that produce a terribly smelly discharge they use as a defense. They have, like all members of this family, with powerful jaws that capture prey.

That smelly liquid is irritating to human skin, and some people with delicate skin dermatitis produce them.
It is also very difficult to get the smell of these insects if
Defensive liquid touches our skin or clothing.

They feed on caterpillars, they are used as biological control have been introduced in some places against pests. Therefore they are considered beneficial insects.

Hello Hernan,
What neat looking beetle with beautiful textured marking. I like the contrasting black and iridescent turquoise colors of it's shell, Awesome detail showing it's unique features off in fine fashion. You managed to capture some great DOF as the entire insect in in sharp focus. Great photo!!

Great shot my friend...it is like a small toy...sharpness is too good and well composed.
