Coleoptera Sentence Examples

The occurrence of weevils - among the most specialized of the Coleoptera - in Triassic rocks shows us that this great order of metabolous insects had become differentiated into its leading families at the dawn of the Mesozoic era, and that we must go far back into the Palaeozoic for the origin of the Endopterygota.

A large and dominant Holoarctic fauna, with numerous subdivisions, ranges over the great northern continents, and is characterized by the abundance of certain families like the Carahidae and Staphylinidae among the Coleoptera and the Tenthredinidae among the Hymenoptera.

The multiplication of orders is attended with practical difficulties, and the distinctions between the various groups of the Linnean Neuroptera are without doubt less obvious than those between the Coleoptera (beetles) and the Diptera (two-winged flies) for example.

The cockroaches, grasshoppers, crickets and other insects that are included in this order were first placed by C. Linne (1735) among the Coleoptera (beetles), and were later removed by him to the Hemiptera (bugs, &c.).

Coleoptera (beetles) supply instances of mimicry of ants, wasps and Ichneumonids, and some defenceless forms of this order mimic others that are protected.

Sometimes Lepidoptera mimic protected members of other orders of insects - such as Coleoptera, Hymenoptera and Hemiptera; but perhaps the most singular illustrations of the phenomenon known in the order are exemplified by the larvae of the hawk-moth Chaerocampa, which imitate the heads of snakes.

The same style of coloration is found in Coleoptera of the families Cetoniidae and Cantharidae; in Diptera of the families Asilidae, Bombylidae, Tabanidae and Tachinidae; in Hemiptera of the family Reduviidae and in Lepidoptera of the family Zygaenidae.

Towards this Lycoid centre have converged Coleoptera (beetles) of the sub-order Lamellicornia (Copridae), Phytophaga; Heteromera (Cantharidae) and Longicornia; Hemiptera of the families Pyrrhocoridae, Lygaeidae and Reduviidae; Lepidoptera of the families Arctiidae and Zygaenidae; Diptera of the family Asilidae; and lastly Hymenoptera of the families Braconidae, Pompilidae, Crabronidae and Eumenidae.

The Brenthidae, Anthribidae and Scolytidae are described in the article Coleoptera.

For a general account of the structure, development and relationships of insects, see Arthropoda and Hexapoda, while details of the form, habits and classification of insects will be found in articles on the various orders or groups of orders (Aptera, Coleoptera, Dipteria,Hemiptera,Hymenoptera,Lepidoptera,Neuroptera, Orthoptera, Thysanoptera), and in special articles on the more familiar divisions (ANT, BEE, Dragon-Fly, Earwig, &c.).

One or two land shells, a few spiders, several Coleoptera, a small lepidopter and a few other insects are recorded, but no Orthoptera or Hymenoptera.

This flexible tube is the functional ovipositor, the typical insectan ovipositor with its three pairs of processes (see Hexapoda) being undeveloped among the Coleoptera.

The occurrence in the hypermetamorphic Coleoptera (see supra) of a campodeiform preceding an eruciform stage in the life-history is most suggestive.

They are bright, iridescent, golden-green or bluish-coloured beetles (see Coleoptera), with the breast finely punctured and pubescent, head and thorax with a longitudinal channel, and elytra with two slightly elevated lines.

The insects belong to the family Elateridae, whose characters are described under Coleoptera.

For the relationship of the Coleoptera to other orders of insects see Hexapoda.

Such a typically "campodeiform" grub, moving actively about in pursuit of prey, is the one extreme of larval structure to be noticed among the Coleoptera.

The Coleoptera are almost worldwide in their distribution, being represented in the Arctic regions and on almost all oceanic islands.

It follows, therefore, that they have been independently acquired in the course of the evolution of the Coleoptera.

The Coleoptera can be traced back farther in time than any other order of insects with complete transformations, if the structures that have been described from the Carboniferous rocks of Germany are really elytra.

The Coleoptera have been probably more assiduously studied by systematic naturalists than any other order of insects.

Students of the Coleoptera have failed to agree not only on a system of classification, but on the relative specialization of some of the groups which'.

Lameere, for example, considers some of his Cantharidif ormia as the most primitive Coleoptera.

In the Coleoptera we have to do with an ancient yet dominant order, in which there is hardly a family that does not show specialization in some point of structure or life-history.

The most interesting of the Heteromera, and perhaps of all the Coleoptera, are some beetles which pass through two or more larval forms in the course of the life-history (hypermetamorphosis).

While from the nature of their life-history there is no doubt that they have a rather close relationship to the Meloidae, their structure is so remarkable that it seems advisable to regard them as at least a distinct tribe of Coleoptera.

C. Miall's Aquatic Insects (London, 1895), the special literature of the Coleoptera is enormous.

Insects abound, especially Coleoptera.

Among the Coleoptera or bettles there is a group of world-wide pests, the Elateridae or click beetles, the adults of the various " wireworms."

In aquatic insects various devices for obtaining or entangling air are found; these modifications are described in the special articles on the various orders of insects (Coleoptera, Hemiptera, &c.).

Among a few of the beetles or Coleoptera, and also in the neuropterous genus Mantispa, are found life-histories in which the earliest instar is campodeiform and the succeeding larval stages eruciform.

His classification was founded mainly on the nature of the wings, and five of his orders - the Hymenoptera (bees, ants, wasps, &c.), Coleoptera (beetles), Diptera (two-winged flies), Lepidoptera (moths and butterflies), and Hemiptera (bugs, cicads, &c.) - are recognized to-day with nearly the same limits as he laid down.

The earwigs, cockroaches and locusts, which Linnaeus included among the Coleoptera, were early grouped into a distinct order, the Orthoptera.

From the Trias of Colorado, Scudder has described cockroaches intermediate between their Carboniferous precursors and their present-day descendants, while the existence of endopterygotous Hexapods is shown by the remains of Coleoptera of several families.

The only doubt arises from the existence of insect remains, referred to the order Coleoptera, in the Silesian Culm of Steinkunzendorf near Reichenbach.

The campodeiform larvae of many Coleoptera are indeed far more primitive than the neuropteran larvae, and suggest to us that the Coleoptera - modified as their wing-structure has become - arose very early from the primitive metabolous stock.

The antiquity of the Coleoptera is further shown by the great diversity of larval form and habit that has arisen in the order, and the proof afforded by the hypermetamorphic beetles that the campodeiform preceded the eruciform larva has already been emphasized.

Further references will be found appended to the special articles on the orders (Aptera, Coleoptera, &C).

In 1735 appeared the first edition of the Systema naturae of Linnaeus, in which the "Insecta" form a group equivalent to the Arthropoda of modern zoologists, and are divided into seven orders, whose names - Coleoptera, Diptera, Lepidoptera, &c., founded on the nature of the wings - have become firmly established.
