Though the Tenebrionidae family is quite large, numbering close to 15,000 species, all darkling beetles share certain characteristics. Cleridae (checkered beetles) are usually oblong or cylindrical, fairly active, and often brightly coloured. The most valuable components of the collection are the comprehensive collections of southern African Curculionoidea (weevils and their close allies), Chrysomelidae (leaf beetles), Bruchida… The ground beetles. Nitidulidae (sap beetles) are short and flattened and have slightly shortened elytra. They are to be found in almost every habitat, and range in size from 1 – 100mm. COLEOPTERA Adults: Coleoptera adults can be recognized primarily by the presence of heavily sclerotized fore wings (elytra) which lack veins and cover the membranous hind wings (Figure 12.2). They have complete metamorphosis. Family Chrysomelidae. Legs with 5 segments (not counting tarsal claw) (Fig. The British Insects by L. Watson and M. J. Dallwitz . The largest of all families, the Curculionidae (weevils), with some 83,000 member species 23 — Dichotomous Keys to Some Families of Florida Coleoptera The order Coleoptera may contain the largest number of described species of any insect order. Coccinellidae (ladybugs, ladybird beetles) are rounded, with a smooth, raised upper surface and a flat underside. 2006. Coleoptera are holometabolus, thus possess distinct egg, larval, pupal, and adult stages. Diversity of Coleoptera families (from Table 11.1). The heaviest known insect is a scarab beetle.

Hlavac, T.F. Beetles of both families may occur in the same habitats, thus are often collected simultaneously. Order Coleoptera.

Coleoptera. They live throughout the world (except Antarctica), but are most speciose in the tropics. They usually have strong mandibles that strike each other in a horizontal plane (>-<).

(1991) found no relationship between the per capita rate of increase of SPB and any of three climatic variables (water deficits, winter temperatures, and summer temperatures). Georgiev, G., and Hubenov, Z.

Order Coleoptera This is the largest order in the class Insecta with over 250,000 described species. Keys to adults of the water beetles of Britain and Ireland. Two pairs of wings on adults, forewings hardened and serve as protective covers (elytra) for hindwings. Three families have aquatic larvae but terrestrial adults, and two families have terrestrial larvae but … Most adults and larvae are substrate dwellers, but some are efficient swimmers (e.g., larval and adult Dytiscidae and Hydrophilidae). Larvae generally appear grub-like with a well-defined head capsule, which may be highly sclerotised. Adult beetles are similar in size and shape, but hydrophilids can be distinguished by: – Characteristically clubbed antennae, which are mostly composed under the head. The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. Entomol., 13th, Moscow, 1: 281. Key to Genera of Elaphidiini. The smallest beetle is the fringed ant beetle, Nanosella fungi (family Ptiliidae). Their eyes are notched. The antennae usually have 11 segments and may be filiform or moniliform. A catalogue of family-group 4887 names. The Coleoptera, with about 400,000 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. The collection houses an estimated number of more than 600 000 beetle specimens and is continually growing . 1 capitalized: the largest order of insects comprising the beetles and weevils and being distinguished by a pair of forewings that are usually hard and rigid, are never used for flight, and serve as a protective covering for the delicate flight wings and the upper surface of … Surface and a pair of membranous hind wings are membranous and folded beneath the elytra, and classifications.
