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.
Antennae, sometimes referred to as "feelers", are paired appendages used for sensing in arthropods.
The telephone-pole beetle is a beetle native to the eastern United States, and the only living representative of the otherwise extinct family Micromalthidae. They have an unusual life cycle involving asexually reproducing (parthenogenetic) female larvae, as well as non-functional "ghost adults".
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns.
Cavognathidae is a family of beetles, in the superfamily Cucujoidea. It contains a single genus, Taphropiestes with around a dozen species known from South America, Australia and New Zealand. In Australian and New Zealand species adults and larvae have been found living in bird nests, but their ecology is unclear, but they are possibly scavengers.
Melandryidae is a family of beetles in the superfamily Tenebrionoidea. Members of the family are found worldwide, with around 420 species in 60 genera. Larvae and adults are generally associated with rotting wood and wood-decomposing fungi.
Eosacantha is an extinct genus of tortoise beetle in the family Chrysomelidae and containing a single species Eosacantha delocranioides. The species is known only from the Middle Eocene Parachute Member, part of the Green River Formation, in the Piceance Creek Basin, Garfield County, northwestern Colorado, USA.
Trictenotoma is a genus of beetle in the Trictenotomidae family. They have scales covering the elytra that fluoresce under ultraviolet light. Based on similarities in the larval characteristics, the family is thought to be closely related to the Salpingidae.
Autocrates is a genus of beetles in the Trictenotomidae family with species across the Indomalayan realm. They are sexually dimorphic with males having longer and more sinuate mandibles.
Nipponoluciola cruciata, known as "genji-botaru" (ゲンジボタル) in Japanese, is a species of firefly found in Japan. Its habitat is small ditches and streams, and its larvae are aquatic. It was formerly known as Luciola cruciata but was revised taxonomically in 2022.
Dmitry Telnov is a Latvian entomologist, biogeographer, and conservationist. He is a fellow and vice president of the Entomological Society of Latvia as well as the executive editor of the "Biodiversity, biogeography and nature conservation in Wallacea and New Guinea" book series, as well as a member of the editorial board of the "Latvijas Entomologs", ZooKeys and Tijdschift voor Entomologie journals. He is primarily known for his taxonomic works on Coleoptera and biogeographic research in the Papuan region and in the Wallacea.
2019 in paleoentomology is a list of new fossil insect taxa that were described during the year 2019, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
2020 in paleoentomology is a list of new fossil insect taxa that were described during the year 2020, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
Coelostoma is a genus of beetles belonging to the family Hydrophilidae. The genus was first described by Brullé in 1835. The genus has cosmopolitan distribution, with 111 described species, representing one of the most diverse genera of Hydrophilidae.
Trictenotoma templetoni, is a species of croc beetle found in Sri Lanka.
Coelostoma (Holocoelostoma) stultum, is a species of water scavenger beetle widely distributed in Palearctic and Oriental realms from West Pacific towards Indian Ocean, such as China, Taiwan, Andaman Islands, Myanmar, India, Indonesia, Japan, Korea, Malaysia, Mascarene Islands, Nicobar Islands, Oman, Philippines, Saudi Arabia, South Korea, Sri Lanka, Thailand, United Arab Emirates, Oman, and Vietnam.
Coelostoma (Coelostoma) vitalisi, is a species of water scavenger beetle found in China, Taiwan, Japan, India, Indonesia, Japan, Malaysia, Nepal, Singapore, Sri Lanka, Cambodia, Thailand and Vietnam.
Binburrum articuno is a species of beetle which in the taxonomy field is classified under the genus Binburrum. It exists only in Australia. It is named after the fictional creature known as Articuno from the pop culture franchise Pokémon. It was named alongside other beetles from the same genus, Binburrum zapdos and Binburrum moltres, by Darren Pollock and Yun Hsiao. Because their names are based on a very popular franchise, these species saw above average media coverage upon being named.
This list of 2023 in paleoentomology records new fossil insect taxa that are to be described during the year, as well as documents significant paleoentomology discoveries and events which occurred during that year.
