The Phalacridae are a family of beetles commonly called the shining flower beetles, They are often found in composite flowers. They are oval-shaped, usually tan, and aboout 2 mm in length. Most species feed on fungus, although a number feed on flower heads.
Cucujoidea is a superfamily of beetles. This group formerly included all of the families now included in the superfamily Coccinelloidea. They include some fungus beetles and a diversity of lineages of "bark beetles" unrelated to the "true" bark beetles (Scolytinae), which are weevils.
Dr Wilhelm Ferdinand Erichson was a trained medical doctor and a German entomologist.
Staphylinoidea is a superfamily of beetles. It is a very large and diverse group with worldwide distribution.
The Zopheridae family of beetles has grown considerably in recent years as the members of two other families have been included within its circumscription; these former families are the Monommatidae and the Colydiidae, which are now both included in the Zopheridae as subfamilies or even as tribe of subfamily Zopherinae. Some authors accept up to six subfamilies here, while others merge all except the Colydiinae into the Zopherinae.
Colydiinae is a subfamily of beetles, commonly known as cylindrical bark beetles. They have been treated historically as a family Colydiidae, but have been moved into the Zopheridae, where they constitute the bulk of the diversity of the newly expanded family, with about 140 genera worldwide. They are diverse for example in the Australian region, from where about 35 genera are known; in Europe, though, only 20 genera are found and many of these only with few species.
Melyridae are a family of beetles of the superfamily Cleroidea.
Melanotus is a genus of click beetles in the family Elateridae. There are at least 30 described species in Melanotus.
Stenus is a genus of semiaquatic rove beetles in the subfamily Steninae, and one of the largest genus in the kingdom Animalia, with some 2700 known species worldwide. They are predators of Collembola and other small arthropods. Adults have a protrusible labium with a sticky tip used in prey capture. To overcome the rapid escape of Collembola, the labium is protruded at high speed by hemolymph pressure, and immediately withdrawn, pulling the prey within the range of the mandibles. However, the labium tip does not easily stick to preys covered in scales or setae or that have a large body size. Stenus comma is more likely to catch such preys by lunging forward and grabbing them directly with its mandibles rather than using its labium. Stenus species are also known for "skimming" on the water surface using their pygidial gland secretions that act as a surfactant and rapidly propel the beetle fast forward, a phenomenon known as the Marangoni effect. Stenus comma has been seen to achieve a velocity of 0.75 m/s, and to cover a distance of up to 15 m if the secretion is continuous.
Xylodromus concinnus is a species of rove beetle in the Omaliinae subfamily, that can be found everywhere in Europe, the Near East, and Australia.
Xylodromus depressus is a brown coloured species of beetle in the rove beetle family, that can be found in Albania, Austria, Belgium, Bulgaria, the Czech Republic, France, Germany, Greece, Hungary, Italy, Poland, Portugal, Romania, Russia, Slovakia, Switzerland, the Netherlands, and Ukraine. It can also be found in the Baltic states, Scandinavian countries and all of the republics of former Yugoslavia.
Xylodromus a genus of beetles in the family Staphylinidae, subfamily Omaliinae.
Xylodromus sassuchini is a species of rove beetle in the Omaliinae subfamily that is endemic to Russia.
Malachius is a genus of soft-winged flower beetles belonging to the family Melyridae subfamily Malachiinae. Malachius species have been reported from Albania, Belgium, Bulgaria, Czech Republic, France, Germany, Hungary, Italy, Poland, Spain, Sweden, Switzerland and in former Yugoslavia.
Stilbus testaceus is a species of beetles commonly called the shining flower beetles belonging to the family Phalacridae.
Cafius bistriatus is a species of relatively large rove beetles in the family Staphylinidae. It can be found from Quebec and Newfoundland to Florida but not yet in South Carolina or Georgia, and in Texas. East of Florida, it occupies Bermuda and the Bahamas. In the Caribbean, it occupies Antigua and Barbuda (Antigua), Barbados, Dominica, Dominican Republic, Grenada (Carriacou), Guadeloupe, Jamaica, Montserrat, Puerto Rico, St. Kitts-Nevis, St. Lucia, Trinidad & Tobago, and U.S. Virgin Islands. It Has been found in the Venezuelan state Falcón. In eastern Mexico, it occurs in Veracruz, Campeche and Quintana Roo. On the Pacific coast, it can be found from California to the Mexican states of Baja California Norte, Baja California Sur, Guerrero, and Sonora. It can grow to be up to 7mm.
Colopterus is a genus of sap-feeding beetles in the family Nitidulidae. There are about 10 described species in Colopterus.
Malachiini is a large tribe of soft-winged flower beetles in the family Melyridae.
