Insect life is represented by plant-bugs, locusts, crickets, grasshoppers, cockroaches, dragon-flies, butterflies, numerous varieties of moths, bees and mosquitoes.
For special treatment towards the regeneration of an infected race, the most robust worms were to be selected, and the moths issuing from the cocoons were to be coupled in numbered cells, where the female was to be confined till she deposited her eggs.
The scandals of the bowling alleys grew rampant in Elizabethan London, and Stephen Gosson in his School of Abuse (1579) says, "Common bowling alleys are privy moths that eat up the credit of many idle citizens; whose gains at home are not able to weigh down their losses abroad; whose shops are so far from maintaining their play, that their wives and children cry out for bread, and go to bed supperless often in the year."
Many larvae of beetles, moths, &c., bore into bark, and injure the cambium, or even the wood and pith; in addition to direct injury, the interference with the transpiration current and the access of other parasites through the wounds are also to be feared in proportion to the numbers of insects at work.
Sugar-canes suffer from the sugar cane borer (Diatioca sacchari) in the West Indies; tobacco from the larvae of hawk moths (Sphingidae) in America; corn and grass from various Lepidopterous pests all over the world.
In butterflies and moths the lacinia is absent while the galea becomes a flexible process, grooved on its inner face, so as to make with its fellow a hollow sucking-trunk, and the palp is usually very small.
Paired erectile plates (patagia) are borne on the prothorax in moths, while in moths, sawflies, wasps, bees and other insects there are small plates (tegulae) - see Fig.
In insects so widely separated as bristle-tails and moths this occurs occasionally.
In moths and certain saw-flies there is no rupture of the membranes; the Russian zoologists Tichomirov and Kovalevsky have described the growth of both amnion and embryonic ectoderm around the yolk, the embryo being thus completely enclosed until hatching time by both amnion and serosa.
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.
Includes the moths and butterflies.
The caterpillars (" cut worms ") of various species of Agrotis and other moths occur in all parts of the world and attack young cotton.
Beneath are the official Liverpool quotations of " futures," as they appeared on the morning of the 19th of April 1906: A merican Deliveries, any port, basis of middling, good ordinary clause (the fractions are given in moths of a penny).
Pliny says that their wood was everlasting, and therefore images of the gods were made of it; he makes mention also of the oil of cedar, or cedrium, distilled from the wood, and used by the ancients for preserving their books from moths and damp; papyri anointed or rubbed with cedrium were on this account called ced ati libri.
That is especially true of the moths (yacho), 100 species of which have been identified with English types.
There are seven large silk-moths, of which two only (Bombyx mon and Anthenaea yama-mai) are employed in producing silk.
Fishing lines are manufacttired from the cocoons of the genjiki-mushi (Caligula japonica), which is one of the commonest moths in the islands.
CADDIS-FLY and Caddis-Worm, the name given to insects with a superficial resemblance to moths, sometimes referred to the Neuroptera, sometimes to a special order, the Trichoptera, in allusion to the hairy clothing of the body and wings.
Butterflies, moths and bees are very abundant, the former being remarkable for their size and splendid coloration; but these groups have not been investigated exhaustively enough to afford a correct idea of their number or their true affinities.
Scorpions and tarantulas are numerous, and lizards, frogs, beetles, ants, butterflies, moths and flies are abundant.
Birds and mammals take the first place; the leading collections devote a good deal of attention to reptiles and batrachians; fishes and aquatic invertebrata are most often to be found only when there are special aquaria, whilst non-aquatic invertebrates are seldom to be seen and at most consist of a few moths and butterflies, spiders, scorpions and centipedes, molluscs and crustaceans.
But the fibres used for manufacturing purposes are exclusively produced by the mulberry silk-moth of China, Bombyx mori, and a few other moths closely allied to that insect.
Such cocoons as are selected for the production of graine, on the other hand, are collected, freed from the external floss, and preserved at a temperature of from 66° to 72° F., and after a lapse of from eleven to fifteen days the moths begin to make their appearance.
Pasteur established (I) that the corpuscles are the special characteristic of the disease, and that these invariably manifest themselves, if not in earlier stages, then in the mature moths; (2) that the corpuscles are parasites, and not only the sign but the cause of the disease; and (3) that the disease manifests itself by heredity, by contagion with diseased worms, and by the eating of leaves on which corpuscles are spread.
He had only to examine the bodies of the moths yielding his graine: if they were free from disease then a crop was sure; if they were infected the education would assuredly fail.
Have appeared till towards the period of transformation and escape of the moths, the eggs subsequently hatched out might be depended on to yield a fair crop of silk; should the moths prove perfectly free from corpuscles after depositing their eggs the next generation would certainly live well through the larval stage.
The insects appeared quickly to revert to natural conditions; the moths brought out in open air were strongly marked, lively and active, and eggs left on the trees stood the severity of the winter well, and hatched out successfully in the following season.
The moths hatch out at a period when oak leaves are not ready for their feeding, and the silk is by no means of a quality to compare with that of the common mulberry worm.
- Among the disadvantages under which the silks of the wild moths long laboured one of the most serious was the natural colour of the silks, and the extreme difficulty with which they took on dyes, specially the light and brilliant colours.
The resemblance that certain moths - e.g.
It is important to note that the scales are present when the moths first emerge from the pupa-case, but are loosely attached and fall off with the first flight.
The insect life comprises many brilliantly-coloured beetles, butterflies (about eight hundred species of which are known), moths, locusts, spiders and flies, and also noxious spiders, with scorpions and centipedes.
The general practice for many years past among naturalists has been to restrict the terms "Insecta" and "insect" to the class of Arthropods with three pairs of legs in the adult condition: bees, flies, moths, bugs, grasshoppers, springtails are "insects," but not spiders, centipedes nor crabs, far less earthworms, and still less slugs, starfishes or coral polyps.
Moths, also, of strange forms and of great size are common.
The leaves of the hazel are frequently found mined on the upper and under side respectively by the larvae of the moths Lithocolletis coryli and L.
Mosquitoes are innumerable, and moths and ants of the most destructive kind, as well as others equally noxious and disagreeable.
In England moth life is practically continuous all the year round, that is, as regards those moths that attack furs, though the destructive element exists to a far greater extent during spring and summer.
Larly abundant; crickets, beetles, locusts, walking-stick insects, mayflies and bugs are found, but there were neither flies, moths, butterflies nor bees, which is no more than we should expect from the conditions of plant life.
The branches are some times attacked by weevils (Rhyn- cites) and the larvae of various moths, and saw-flies (chiefly Erio- campa) feed on the leaves, and young branches and leaves are sometimes invaded by Aphides.
Leaf-feeding beetles and larvae of moths are best got rid of by shaking the branches and collecting the insects.
This type of colouring is also found in genera of quite distinct sub-families of butterflies, namely in Danainae and Pierinae, as well as in some diurnal moths, all of which occur in the same district as the Ithomiinae.
The moths yielding wild silks which have obtained most attention belong to the extensive and handsome family Saturnidee.
