Bledius annularis, or ringed borrow rove beetle, [1] is a species of spiny-legged rove beetle in the family Staphylinidae. [2] [3] [4] [5] It is found in North America. [3]
The lectotype for this taxon from a male specimen, collected from Lake Superior, and is housed within the Museum of Comparative Zoology at Harvard University. [6]
Within New Brunswick, B. annularis is characteristically known to frequent damp clay riverbanks and shaded streams. [7]
A number of closely related species of Bledius are commonly grouped together and referred to as the "annularis complex", then further subdivided into the "annularis group". This 'complex' of difficult to distinguish species is distributed right across northern North America, and consists of B. annularis, B. breretoni, B. honestus, B. languidus, B.mysticus, B. nebulosus, B. sinuatus, B. stabilis, and B. washingtonensis. [8] : 93
The beetle is slender and elongate in appearance, measuring between 3.8 mm and 4.5 mm. Its head and thorax, as well as the tip of its abdomen are all black in colour, whilst the base of its abdomen, its elytra and its antennae are reddish-brown. Its legs are dark yellow. Its head is lightly granulate and also finely punctate. The thorax is not as wide as it is long, whilst the base of the abdomen is narrower than the elytra. The abdomen of this beetle sometimes appears slightly banded as a result of the hind margins of the upper (dorsal) segments being slightly darker in colour. [9]
Beetles are insects that form the order Coleoptera, in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. 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.
The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is the largest family in the beetle order, and one of the largest families of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus Leehermania proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems.
The devil's coach-horse beetle is a species of beetle belonging to the large family of the rove beetles (Staphylinidae). It was originally included in the genus Staphylinus in 1764, and some authors and biologists still use this classification.
Pselaphinae are a subfamily of beetles in the family Staphylinidae, the rove beetles. The group was originally regarded as a separate family named Pselaphidae. Newton and Thayer (1995) placed them in the Omaliine group of the family Staphylinidae based on shared morphological characters.
Paederus is a genus of small beetles of the family Staphylinidae. With 622 valid species assigned by 1987 to the subtribe Paederina, and with all but 148 within Paederus itself, the genus is large. Due to toxins in the hemolymph of some species within this genus, it has given its name to paederus dermatitis, a characteristic skin irritation that occurs if one of the insects is crushed against skin. That name, Paederus dermatitis, is a poor choice because, decades earlier, the affliction had been called dermatitis linearis, a name that works in all languages, not just English, because of its Latin origin; the name Paederus dermatitis is also inappropriate because it has shown to be caused by (a) only a few species of the genus Paederus, but (b) also a few species that belong to closely related genera within the subtribe Paederina. A scholarly paper in 2002 suggested that a Paederus species could have been responsible for some of the ten Plagues of Egypt described in the Bible's Book of Exodus.
Dasycerinae is a subfamily of rove beetles. Dasycerinae currently only contains 1 extant genus and 3 extinct genera.
The Empelinae are a subfamily of rove beetles ; their biology is virtually unknown. Their anatomy and ecology resemble many rove beetles.
The Oxytelinae are a subfamily of the Staphylinidae, rove beetles. There are about 20 genera and at least 320 described species in Oxytelinae.
