Feather like flabellate antennae are a restricted form found in the Rhipiceridae and a few other families. The Silphidae have a capitate antennae with a spherical head at the tip.
Eleodes (commonly known as pinacate beetles or desert stink beetles) is a genus of darkling beetles, in the family Tenebrionidae. [1] They are endemic to western North America ranging from southern Canada to central Mexico with many species found along the Mexico-United States border. [2] Some species have been introduced to Colombia.
European bark beetle predators, Glischrochilus quadripunctatus, are predators of the larvae of wood-boring insects, particularly bark beetles. [6]Glischrochilus beetles from the subgenus Librodor, consisting the majority of species in the genus, feed on exuding sap from injured trees and decaying vegetable or fungal matter.
The rove beetles are a family (Staphylinidae) of beetles, [2] primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed.

Around two hundred and fifty species of heterocerids are known to occur worldwide. [1] They are most diverse in tropical and sub-tropical regions.
The family includes spider beetles and deathwatch beetle, [2] as well as the cigarette, drugstore and furniture beetles. The Ptinidae family species are hard to identify because they are so small, and they have a compact body structure. They also have similar morphologies within the genera and species of the family.

The family is among the largest of the beetles, with some 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described. [1]
Ground beetles are a large, cosmopolitan family of beetles, [2] the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. [3] As of 2015, it is one of the 10 most species-rich animal families.
