The Histerinae contains 5 tribes and more than half of all known species of the family. In Cuba several species of Carcinops occur in caves. DENDROPHILINI Reitter, 1909 The limits of this tribe are still to be worked out; it was for a long time considered to include two genera, Dendrophilus Leach, 1817 and Kissister Marsuel, 1862, but now it seems that the latter might be more appropriately placed within the Paromalini. in the Central American genus Trypaneus the thorax is very elongate, about twice the length of the elytra. Many occur under bark and some North American species of Carcinops Marseul, 1855 are associated with cacti. Hister Linnaeus, 1758 and Margarinotus Marseul, 1854. The beetles have been recorded in colonies of ant species scattered across the subfamilies Dolichoderinae, Dorylinae, Formicinae, Myrmicinae and Ponerinae (Helava et al., 1985; Tishechkin, 2007) (Figure 3). -This clown beetle often occur in large numbers at any time of the year, all over the world. There are at least 60 described species in Paromalus., Reimagined by Gibon, design of warm cheerful glowing of brightness and light rays radiance. The elytra are often (usually) truncate and almost always shorter than the abdomen, generally leaving two tergites, the pygidium and the propygidium, exposed. Most have specialized heads that can be retracted into or under the prothorax. Amongst their characteristic traits are their shiny metallic wings. Tarsi: 5-5-5. Introduction. The bottomless pit of insect biodiversity has yielded a treasure trove of new species of jewel-like clown beetles… These tiny black beetles can be found making homes anywhere and out of anything. A small subfamily of 3 genera; Pygocoelis Lewis, 1897 with 10 species and Trypobius Schmidt, 1893 with 2 species are African while more than 100 species of Trypeticus Marseul, 1864 occur in South East Asia, especially China, and Australia. Sphaerites is a genus of beetles, the only genus in the family Sphaeritidae, sometimes called the false clown beetles.It is closely related to the clown beetles but with distinct characteristics. Hister beetles, also known as Clown beetles because of their flattened legs, represent a quite diverse family (Histeridae) of beetles living almost everywhere around the world. Possible Genus Zeadolopus. Photo notes: climbing on tree bark. Some species of Hister Beetle live in trees, others in abandoned rodent burrows. Histerids generally arrive late at carrion and dung, after other species have colonized the habitat, so that a food source is available. Part 24. Genus Saprinus. Carcinops pumiliohas a broad world distribution and is associated with wild bird nests and bat guano piles. Adults and larvae predatory on other insects (such as maggots), other small invertebrates. The large genus Saprinus Erichson, 1834 is mostly from the Old World; of more than 160 species only 9 occur in North America. Mason Neck, Fairfax County, Virginia. Porrostoma rhipidium. Most species are associated with decaying vegetation; compost and litter etc. Teretriosoma conigerum is a species of clown beetle in the family Histeridae. The histerid beetle genus Baconia is distinguishable by the peculiar flat shape and the metallic body coloration ranging between beautiful blue, green and violet tones. Several of the genera are very large and widely distributed e.g. Members of the subfamily are mostly broad and somewhat parallel-sided, flattened dorsally and ventrally, and possess distinct and often exaggerated sculpture to the pronotum and elytra. Fairly consistent characters seem to be the well developed prosternal lobe which is dilated and covers the antennal cavities when the beetle is rolled up, and the lack of labral setae. This family of beetles will occupy almost any kind of nichethroughout the world. The new species and genus Iridoprinus myrmecophilus is the first known myrmecophilous saprinine for the Australopacific Region. Hydrophilidae (Water Beetles) Leiodidae (Round Fungus Beetles) Genus Paragyrtodes. In most species the scutellum is hidden by a basal expansion of the pronotum. The widespread C. pumilo (Erichson, 1834) occurs among rotting vegetation and dung. Size Range: 1-10mm. -The body size is usually between 1/8 - 3/8'' long. Lycidae (Lycid Beetles) Genus Calochromus.

Photography inspired by futurism, embracing dynamic energy of modern technology, movement, … They are small, convex and broadly elongate beetles. While there are genera in other subfamilies with a similar overall morphology, species of Niponius are unique in possessing a large, elongate head with produced frontal processes and ventrally deflexed mandibles. About 30 species occur in the Palaearctic and Nearctic regions, and the group is particularly diverse in the Neotropical region. The antennal scape is short and dilated, usually almost triangular. They are drab; mostly dark brown, smooth, shiny and punctured. Sphaerites is a genus of beetles, the only genus in the family Sphaeritidae, sometimes called the false clown beetles. Promyrmister kistneri gen. et sp. Some species of Hister Beetle live in trees, others in abandoned rodent burrows. If you need expert professional advice, contact your local extension office. Genus Platysoma. Porrostoma simsoni. has been recorded from a rats nest. Add your article. Many are endemic to the deserts of North Africa and Central Asia. Meloidae (Blister Beetles) Mycteridae (Palm and Flower Beetles) … Pinacate Beetle Beetles in the genus Eleodes are known as "darkling" or "pinacate beetles," and colloquially as "stinkbugs" or "clown beetles." Some species are myrmecophilous. It is by Whitney Cranshaw at Colorado State University. Esox americanus, a type of fish. Because the subfamilies display various forms and lifestyles they are described separately, and briefly, below. They are saproxylic with many species inhabiting the tunnels of other insects. The prosternum nearly always has impressed lines, generally longitudinal, on the surface and these often provide useful diagnostic characters for the species. ~440 spp. Many are nocturnal and the majority, if not all, of histerids can fly well. But stink bugs can be a real nuisance and cause alarm when they appear on draperies, blinds, lights, or even buzzing around one's head in the home. The prosternum has cavities for the reception of the antennae when the beetle is ‘rolled up’, these are either anterior, behind the front margin, or posterior, and their position is often a useful aid in identification. The clypeus and frons are smooth; without a suture, and the clypeus is prolonged into a ‘snout’. This subfamily  is closely related to the Abraeinae and includes 3 genera and around 80 species of highly specialized saproxylic beetles that live in the burrows of other wood boring insects. Many species are rather quadrate and smooth with distinct, if sparse, pubescence which often forms rows on the elytra. … Saprinus pennsylvanicus (Clown Beetle) CLOWN BEETLE-The saprinus pennsylvanicus has an oval or rounded, shiny metallic green colored body. in 58 genera in our area, ca.

The family have truncate elytra, leaving the final two abdominal segments exposed, and characteristic geniculate (elbowed) antennae with terminal clubs. Acritus nigricornis (Hoffman,J.) Curiously, the Clown beetles tend to play dead when threatened. They are mostly heavily sclerotized species; diverse in form ranging from oval and convex (typical of Histerini Gyllenhal, 1808, with 26 genera, all >4mm), elongate cylindrical (typical of Exosternini Bickhardt, 1914, a very speciose group) to very flattened and adapted to a saproxylic lifestyle (typical of Hololeptini Hope, 1840 with 6 genera). Adult in defensive posture All British species are small, 1-2.5mm, most are convex and smooth, without or with only rudimentary elytral striae. Darkling is a common name applied to several genera and over 1400 species within the family Tenebrionidae. in ~330 genera worldwide, Small to medium-sized, compact, sturdy beetles, typically black and shiny (a few are brightly colored).

Everything else copyright © 2003-2020 Iowa State University, unless otherwise noted. Many are endemic to the deserts of North Africa and Central Asia. Genus Trichalus . Some species exhibit exaggerated morphology e.g. This form of prosternal structure is also seen in many Histerinae but the present subfamily is distinguished by the presence of a pair of labral setae which are absent in that group. He got his start sometime in the 1940s, when he ran the studio Alfa Circus Film. The beetles are native to North and South America and the discovery brings the total number of beetles belonging to the genus Baconia to 116.
