Cucujus Grouvellei
''Cucujus'' is a genus of beetles in the family Cucujidae, the flat bark beetles. It contains 19 currently recognized species and subspecies. Description Species of ''Cucujus'' are of moderate size (6-25mm), greatly dorso-ventrally compressed, and brightly colored, often red or red and black. Additionally, they can be distinguished from other members of the family by the head being generally wider than the pronotum with prominent temples, and the elongate, inverted male genitalia with a flagellum. The genus occurs throughout the Holarctic region, with indigenous species in North America, Europe, and Asia. It is most diverse in Asia. Ecology The biology of most species in the genus is poorly known. All life stages live under dead bark, where they apparently are predacious. Larvae also are dorso-ventrally compressed. ''Cucujus clavipes puniceus'', which occurs in western North America, has been the subject of considerable research interest due to its ability to produce natural anti ...

Beetles Of North America
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 arthropods 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. However, the number of beetle species is challenged by the number of species in dipterans (flies) and hymenopterans (wasps). 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 (ladybirds or ladybugs) eat ...

Cucujoidea Genera
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 (superfamily Curculionoidea). Morphology The morphology of Cucujoidea is varied and there are no features uniting all members of the superfamily. In terms of general appearance, they tend to be small, drab in colour and with clubbed antennae. Even this is not universal; for example, ''Glischrochilus'' (Nitidulidae) have aposematic orange spots on their elytra. Adults can be recognised by the procoxal cavities being internally open in most taxa, females having tarsal formula 5-5-5 and males 5-5-5 or 5-5-4 (rarely 4-4-4), females with tergite VIII concealed dorsally by tergite VII, and males with tergite X completely membraneous. Larvae have frontal arms usually lyriform, the mandible mesal surfac ...
