Cryptocephalus virens is a cylindrical leaf beetle belonging to the family Chrysomelidae, subfamily Cryptocephalinae. The species was first described by Christian Wilhelm Ludwig Eduard Suffrian in 1847.
The females are usually slightly larger than the males. The colour of the head, pronotum and elytra is metallic green in the females, while in males the elytra are usually metallic blue. Adult beetles live from May to June, feeding mainly on nectar of Asteraceae species.
These beetles can be found in southern and central Europe from the Italian Alps and Bavaria to southern Poland, Russia, Turkey, the east Palearctic realm and the Near East. They prefer hilly and mountainous regions.
Beetles are 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 described 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, 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.
Cetonia aurata, called the rose chafer or the green rose chafer, is a beetle, 20 millimetres long, that has a metallic structurally coloured green and a distinct V-shaped scutellum. The scutellum is the small V-shaped area between the wing cases; it may show several small, irregular, white lines and marks. The underside of the beetle has a coppery colour, and its upper side is sometimes bronze, copper, violet, blue/black, or grey.
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.
The Hercules beetle is a species of rhinoceros beetle native to the rainforests of Central America, South America, and the Lesser Antilles. It is the longest extant species of beetle in the world, and is also one of the largest flying insects in the world.
The Eumolpinae are a subfamily of the leaf beetles, or Chrysomelidae. It is one of the largest subfamilies of leaf beetles, including more than 500 genera and 7000 species. They are oval, and convex in form, and measure up to 10 mm in size. Typical coloration for this subfamily of beetles ranges from bright yellow to dark red. Many species are iridescent or brilliantly metallic blue or green in appearance.
The Cassidinae are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra.
Chrysolina cerealis, the rainbow leaf beetle or Snowdon beetle, is a beetle belonging to the family Chrysomelidae.
Chrysolina americana, common name rosemary beetle, is a species of beetle belonging to the family Chrysomelidae.
Galeruca tanaceti is a species of leaf beetle found in the Palearctic realm, and is the type species of the genus Galeruca. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Chrysochus auratus, the dogbane beetle, of eastern North America, is a member of the leaf beetle subfamily Eumolpinae. It is primarily found east of the Rocky Mountains. Its diet mainly consists of dogbane (Apocynum), specifically Apocynum cannabinum and Apocynum androsaemifolium, and occasionally it eats milkweed. It is 8-11 mm long and has a convex, oval shape.
Acromis spinifex is a species of tortoise beetle from South America. The males have enlarged elytra which are probably used in male–male combat, while females are among the few tortoise beetles to show maternal care of their offspring.
Syneta betulae is a species of beetle from the family of leaf beetles, subfamily Synetinae.
Cryptocephalus marginatus is a cylindrical leaf beetle belonging to the family Chrysomelidae, subfamily Cryptocephalinae. The species was first described by Johan Christian Fabricius in 1781.
Cassida viridis, common name green tortoise beetle, is a species of beetle in the leaf beetle family (Chrysomelidae).
Ips is a genus of beetles in the family Curculionidae, the true weevils. They are bark beetles, members of the subfamily Scolytinae. Species are distributed throughout the Northern Hemisphere. Some are known as introduced species in Australia and Africa. Many species are pests of forest trees, especially pines and spruces. They are known commonly as engraver beetles, ips engraver beetles, and pine engravers.
Chrysophora chrysochlora, the Shining leaf chafer beetle, is a species of beetles of the scarab beetle family.
Scolytus scolytus, the larger European elm bark beetle or large elm bark beetle, is a 3.5–6 mm long bark beetle species. It is of significant importance in Eurasia as a vector of Dutch elm disease.
Acronymolpus is a genus of leaf beetles in the subfamily Eumolpinae. It is endemic to New Caledonia. There are two species placed in the genus, both of which are sexually dimorphic; the females are large and reddish, and the males are small and black. A member of the tribe Eumolpini, Acronymolpus is distinguished from other members of the tribe in New Caledonia by its enlarged metacoxae, which occupy most of the first abdominal ventrite and nearly reach its posterior margin.
Coniomma is a genus of leaf beetles in the subfamily Eumolpinae. It contains only one species, Coniomma hospes, and is endemic to the island of Luzon in the Philippines. The genus and species were first described by Julius Weise in 1922, and were re-described in 2011 by A. G. Moseyko. The genus is very closely related to Rhyparida, from which it is separated mainly by the shape of the eyes and the length of the antennae.
Chrysochus asclepiadeus is a member of the leaf beetle subfamily Eumolpinae. It is considered the type species of the genus Chrysochus, though it has sometimes been placed within the genus Eumolpus. It is the only species of Chrysochus distributed in the western Palaearctic. It is mainly found in Europe, though it is also known from Kazakhstan and Turkey in Asia.
