Piesmus submarginatus is a species of beetle in the family Carabidae, the only species in the genus Piesmus. [1]
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 70,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
Their habitat is under dead pine bark in mesophilous forests. [2]
Calathus is a genus of ground beetle native to the Palearctic, the Near East and North Africa. There are at least 190 described species in Calathus.
Calosoma is a genus of large ground beetles that occur primarily throughout the Northern Hemisphere, and are referred to as caterpillar hunters or searchers. Many of the 167 species are largely or entirely black, but some have bright metallic coloration. They produce a foul-smelling spray from glands near the tip of the abdomen. They are recognizable due to their large thorax, which is almost the size of their abdomen and much wider than their head.
Bembidion is the largest genus of beetles in the family Carabidae by number of species. All species are small and move very fast. Most of them live close to water. The genus has a biantitropical distribution, meaning they are found in both the Northern and Southern Hemispheres, but not in the tropics. In warmer regions it is substituted by closely related Tachys and other genera.
Nebria is a genus of ground beetles native to the Palearctic, the Near East and North Africa.
Clivina is a genus of ground beetle native to the Palearctic, the Nearctic, the Near East and North Africa. There are at least 580 described species in Clivina.
Chlaenius is a large and diverse genus of ground beetle. It is native to the Palearctic, the Near East, North Africa, Afrotropical region, and the Nearctic. Worldwide, roughly 1,000 species are currently recognized with the majority of known species occurring in the Oriental and Afrotropical regions. The genus is divided into many subgenera.
