Such larvae, and also many with soft cuticle and swollen abdomen - those of the notorious "Colorado beetle," for example - feed openly FIG.
Insects are numerous, and of about 500 species of beetle some 80% are not known to exist elsewhere; cockroaches and green locusts are pests, as are, also, mosquitoes,' wasps, scorpions, centipedes and white ants, which have all been introduced from elsewhere.
In the same island a species of Gryllacris mimics Pheropsophus aquatus, a " Bombardier " beetle which ejects a puff of volatile formic acid when attacked; and Condylodera tricondyloides mimics different species of tiger-beetles (Cicindelidae) at different stages of its growth.
The front wings of the wasp have a conspicuous white patch near the tip and a patch similar in size and colour is present on the wings of the beetle, which, unlike the majority of beetles, habitually keeps its wings extended, and since the elytra are exceptionally short the wings are not covered by them when folded.
When beetles, or medusae, or cats vary, the range of possible variation is limited and determined by the beetle, medusa or cat constitution, and any possible further differentiation or specialization must be in a sense at least orthogenetic - that is to say, a continuation of the line along which the ancestors of the individual in question have been forced.
An account of Colorado agriculture would not be complete without mentioning the depredations of the grasshopper, which are at times extraordinarily destructive, as also of the "Colorado Beetle" (Doryphora decemlineata), or common potato-bug, which has extended its fatal activities eastward throughout the prairie states.
The so-called "beetle-stones" of the coal-formation of Newhaven, near Leith, which have mostly a coprolite nucleus, have been applied to various ornamental purposes by lapidaries.
Usually the mother-beetle makes a fairly straight tunnel along which, at short intervals, she lays her eggs.

Similarly the newly-hatched larva of an oil-beetle (Meloe) is an active little campodeiform insect, which, hatched from an egg laid among plants, waits to attach itself to a passing bee.
In Great Britain the beetle, after completing its development, winters in the seed, waiting to emerge and lay its eggs on the blossom in the ensuing spring.

The former attacks apple and pear; the latter, which selects orange and citron, was introduced into America from Australia, and carried ruin before it in some orange districts until its natural enemy, the lady-bird beetle, Vedalia cardinalis, was also imported.
When on the watch for prey the spider slightly raises the lid and, peeping through the chink, darts like a flash upon any beetle or fly that unwittingly passes within reach.
Moniliformis has for its larval host the larvae of the beetle Blaps mucronata, for its final host certain mice, if introduced into man it lives well: E.
P. sylvestris in Britain is liable to many insect depredations: the pine-chafer, Hylurgus piniperda, is destructive in some places, the larva of this beetle feeding on the young succulent shoots, especially in young plantations; Hylobius abietis, the fir-weevil, eats away the bark, and numerous lepidopterous larvae devour the leaves; the pine-sawfly is also injurious in some seasons; the removal of all dead branches from the trees and from the ground beneath them is recommended, as most of these insects lay their eggs among the decaying bark and dead leaves.
51) are those of a terrestrial Arthropod, such as a beetle; whilst those of the Silurian scorpion are the legs of an aquatic Arthropod, such as a crab or lobster.
The latter is the more serious, as in addition to the actual damage done by the beetle the holes afford entrance to fungus spores, &c. Under the name " horn worms " are included the larvae or caterpillars of species of Protoparce.
Stored tobacco is liable to be attacked and ruined by the " cigarette beetle," a cosmopolitan insect of very varied tastes, feeding not only on dried tobacco of all kinds, including snuff, but also on rhubarb, cayenne pepper, tumeric, ginger, figs and herbarium specimens.
Betel, connected with "beat") comes "beetle" in the sense of a mallet, and the "beetling-machine," which subjects fabrics to a hammering process.
Again, galls may afford harbour to insects which are not essentially gall-feeders, as in the case of the Curculio beetle Conotrachelius nenuphar, Hbst., of which one brood eats the fleshy part of the plum and peach, and another lives in the " black knot " of the plum-tree, regarded by Walsh as probably a true cecidomyidous gall.
There is also an American beetle, the Ambrosia beetle, belonging to the family of Swlytidae, which derives its name from its curious cultivation of a succulent fungus, called ambrosia.
A good illustration of wasp-mimicry is furnished by a large heteromerous beetle (Coloborhombus fasciatipennis) from Borneo which is remarkably like a large wasp (Mygnimia aviculus) from the same island.
Similar modification of the antennae in the Longicorn Estigmenida variabilis brings about the resemblance between this beetle and a beetle, Estigmena chinensis, one of the Phytophaga of the family Hispidae.
There are many varieties of beetle, including a number of species representing the scarabaeus of the ancients.
The "` bacon beetle" (Dermestes lardarius), and its hard hairy larva, are well known.
Of this total no less than $40,000,000 (8,000,000) is credited to a small beetle, the cotton boll weevil, and to two caterpillars.
The flex nitive animal gods are not to be confused with the animal not ns ascribed to many cosmic deities; thus when the sun-god Osii was pictured as a scarabaeus, or dung-beetle, rolling its ball Isis lung behind it, this was certainly mere poetical imagery.
For example, the grub of a pea or bean beetle (Bruchus) is hatched, from the egg laid by its mother on the carpel of a leguminous flower, with three pairs of legs and spiny processes on the prothorax.
Boring grub of a longhorn-beetle or of the saw-fly Sires, with its stumpy vestiges of thoracic legs; the large-headed but entirely legless, fleshy grub of a weevil; and the legless larva, with greatly reduced head, of a bee.

Stridulating organs among beetle-larvae have been noted, especially in the wood-feeding grub of the stag-beetles (Lucanidae) and their allies the Passalidae, and in the dung-eating grubs of the dor-beetles (Geotrupes), which belong to the chafer family (Scarabaeidae).
Kowalevsky or a bug is invaginated into the yolk at the head end, the portion of (1871 and 1887) on the embryology of the water-beetle Hydrophilus the blastoderm necessarily pushed in with it forming the amnion.
In the Colorado beetle (Doryphora), whose development has been studied by W.
(The feelers and legs are cut short.) years; (2) certain stages of the life that are naturally " resting stages " may be in exceptional cases prolonged, and that to a very great extent; in this case no food is taken, and the activity of the individual is almost nil; (3) the life of certain insects in the adult state may be much prolonged if celibacy be maintained; a female of Cybister roeselii (a large water-beetle) has lived five and a half years in the adult state in captivity.
The latterfor which the generic term in Japan is mushi or kaichinclude some beautiful species, from the jewel beetle (tama-mushi), the gold beetle (kogane-mushi) and the Chrysochroa fulgidissima, which glow and sparkle with the brilliancy of gold and precious stones, to the jet black Melanauster chinensis, which- seems to have been fashioned out of lacquer spotted with white.

This may, however, be an instance of Miillerian rather than of Batesian mimicry, the beetle being itself inedible; for Shelford has stated his conviction that the Bornean representatives of the sub-family (Clytinae), to which Clytus arietis belongs, are all highly distasteful and are warningly coloured, as are members of this sub-family from other parts of the world.
The oak in Europe is liable to injury from a great variety of insect enemies: the young wood is attacked by the larvae of the small stag-beetle and several other Coleoptera, and those of the wood-leopard moth, goat moth and other Lepidoptera feed upon it occasionally; the foliage is devoured by innumerable larvae; indeed, it has been stated that half the plant-eating insects of England prey more or less upon the oak, and in some seasons it is difficult to find a leaf perfectly free from their depredations.

The elytra are equally reduced, and apparently for the same purpose, in an Australian Longicorn beetle (Esthesis ferrugineus), which, like so many wasp-like Hymenoptera, has the body banded red and black.
Sharp; in the stag-beetle larva a series of short tubercles on the hind-leg is drawn across the serrate edge of a plate on the haunch of the intermediate legs, while in the Passalid grub the modified tip of the hind-leg acts as a scraper, being so shortened that it is useless for locomotion, but highly specialized for producing sound.
Some of the scavengers, like the burying beetles, inter the bodies of small vertebrates to supply food for themselves and their larvae, or, like the "sacred" beetle of Egypt, collect for the same purpose stores of dung.
More thunder boomed. Katie wondered what other kinds of storms the underworld might have. Would it rain something other than black water? With her luck, it'd rain bugs, like the beetle nest she skirted.
