Glischrochilus quadripunctatus, commonly known as the European bark beetle predator is a species of beetle in the genus Glischrochilus of the family Nitidulidae. [1]
The species is approximately 4–6 mm in length and is a uniform dark colouration on its head, thorax and abdomen. It has four prominent orange blotches on the elytra. The body of G. quadripunctatus is smooth and shiny and the rear edge of the thorax is narrower than the elytra. [2]
It is very similar in appearance to Glischrochilus hortensis . [2]
It is one of the three species of Glischrochilus found in the United Kingdom [3] and has a wide distribution in England, Wales, and Scotland. [1]
It is active all-year round, but most often found in the months March to November around conifers. [2]
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. Some others also have unusual characteristics, such as fireflies, which use a light-emitting organ for mating and communication purposes.
The sap beetles, also known as Nitidulidae, are a family of beetles.
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research.
Harmonia axyridis is a large lady beetle or ladybug species that is most commonly known as the harlequin, Asian, or multicoloured Asian lady beetle. This is one of the most variable species in the world, with an exceptionally wide range of colour forms. It is native to eastern Asia, but has been artificially introduced to North America and Europe to control aphids and scale insects. It is now common, well known, and spreading in those regions, and has also established in Africa and widely across South America. This species is conspicuous in North America, where it may locally be known as the Halloween beetle, as it often invades homes during October to overwinter.
The tansy beetle is a species of leaf beetle. The common name derives from its main foodplant, tansy, but it can also use other wetland plants such as gypsywort and water mint. It measures 7.7–10.5 mm in length and has a characteristic bright metallic green colouration, with pitted elytra and a coppery tinge. In addition to the nominotypical subspecies, which repeats the specific name, C. graminis graminis, there are five further distinct subspecies of tansy beetle, which, collectively, have a Palearctic distribution, although in the majority of countries where it is found the species is declining. In the United Kingdom it is designated as 'Nationally Rare'. The stronghold population here is located along the banks of the river Ouse in York, North Yorkshire. Other, small, fenland populations exist at Woodwalton Fen and at Welney Wildfowl and Wetlands Trust (WWT) reserve.
Dermestidae are a family of Coleoptera that are commonly referred to as skin beetles. Other common names include larder beetle, hide or leather beetles, carpet beetles, and khapra beetles. There are over 1,800 species described.
Dynastes tityus, the eastern Hercules beetle, is a species of rhinoceros beetle native to the Eastern United States. The adult's elytra are green, gray or tan, with black markings, and the whole animal, including the male's horns, may reach 60 mm (2.4 in) in length. The larvae feed on decaying wood from various trees.
The scarlet lily beetle, red lily beetle, or lily leaf beetle, is a leaf beetle that eats the leaves, stem, buds, and flowers, of lilies, fritillaries and other members of the family Liliaceae. It lays its eggs most often on Lilium and Fritillaria species. In the absence of Lilium and Fritillaria species, there are fewer eggs laid and the survival rate of eggs and larvae is reduced. It is now a pest in most temperate climates where lilies are cultivated.
Chrysolina cerealis, the rainbow leaf beetle or Snowdon beetle, is a beetle belonging to the family Chrysomelidae.
Athous haemorrhoidalis is a species of European and Asian click beetles in the genus Athous. Several variations are recognized.
Oiceoptoma noveboracense is a member of the family Silphidae, or carrion beetles, which feed on decaying organic matter such as dead animals. Its common name is the margined carrion beetle, from the orange-red margins on the pronotum, which are helpful when identifying this species. The larva is typically light brown to red and also has vertical ridges on its thorax like the adult. This diurnal beetle can be found mainly in the spring into the fall, and it has a strong preference towards a deciduous forest habitat. The primary forensic importance of this beetle is its ability to use the succession of insect fauna to provide confirmation of postmortem intervals.
Carabus violaceus, sometimes called the violet ground beetle, or the rain beetle is a nocturnal species of a beetle, from the family Carabidae.
Megalodacne is a genus of fungivorous beetles in the family Erotylidae.
Glischrochilus[note 1] is a genus of sap-feeding and predatory beetles under the family Nitidulidae, subfamily Cryptarchinae. Most members of this genus are commonly known as picnic beetles or beer bugs.
Aepus marinus is a species of beetle in the family Carabidae. It is found in the intertidal zone of marine habitats in northwestern Europe where it lives in crevices and under stones. The adult beetle is about 2.5 mm (0.1 in) in length, and is a reddish-yellow colour.
Phrynocris notabilis is a species of beetle in the family Cerambycidae, the only species in the genus Phrynocris. The species was originally described by Henry Walter Bates in 1867.
Zographus oculator, the Orange-eyed Long-horn Beetle, is a species of flat-faced longhorn beetles belonging to the family Cerambycidae.
Glischrochilus hortensis is a species of beetle in the genus Glischrochilus of the family Nitidulidae. The genus are commonly known as 'sap-beetles'.
Cionus hortulanus is a species of weevils belonging to the family Curculionidae, subfamily Curculioninae.
