Tenebrionidae

I already posted a specimen from Tenebrionidae, however this is a very common species of Tenebrionidae, and I felt compelled to share. Unlike the other specimen I posted, this species has no hair-like extensions on the elytra (top abdominal shell). Most of the members of Tenebrionidae are absent of hair (setae). Members of Tenebrionidae are also known as Darkling Beetles, and their pupa are various meal worms.

Coleoptera; Polyphaga; Tenebrionoidea; Tenebrionidae; Opatrinae; Eleodes dentipes
Common Name: Darkling Beetle, "Stink Bug" (misnomer)

These insects are commonly mistaken as "Stink Bugs" when they are neither bugs (order Hemiptera, compared to order Coleoptera), nor is that their official common name. An example of a stink bug can be seen here. True stink bugs come in colors ranging from green, to brown, to black and red. The insect pictured above is most likely associated with stink bugs because if disturbed it raises its pointed abdomen into the air as if to spray a chemical, and when crushed they smell very unpleasant. I am not positive on my identification of the species, but the genus is definitely Eleodes. They can be differentiated from Carabidae, another common family of ground beetles, by having a body raised off the ground and small jaws.
