The winged insect differs considerably in form from its sub-aquatic condition.
The other half numbered in the hundreds. The winged demons hovered around the portal and then took off in separate directions, swooping low above the jungle.
The cones, about the size of a small walnut, bear spirally arranged imbricated scales which subtend the three-angled winged seeds.
The male scales differ in form from the female; the adult male is winged, and is rarely seen.
A, Winged female; B, winged D, viviparous wingless female from in patches from old apple trees, where the insects live in the rough bark and form cankered growths both above and below ground.
Among the Hexapoda generally there is no subsequent ecdysis nor any further growth after the assumption of the winged state.
After a prolonged aquatic larval and nymphal life-history, the winged insect appears as a sub-imago, whence, after the casting of a delicate cuticle, the true imago emerges.
The division of the winged Hexapoda into Exopteryga and Endopteryga is thus again justified.
The extreme of this " division of labour " is seen, in those insects whose jaws are vestigial in the winged state, when, the need for feeding all behind them, they have but to pair, to lay eggs and to die.
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.
Hence the grouping of the orders of winged Hexapoda into the divisions Exopterygota and Endopterygota, as suggested by D.
Sharp's proposed association of the parasitic wingless insects in a group Anapterygota cannot, however, be defended as natural; and recent researches into the structure of these forms enables us to associate them confidently with related winged orders.
This phenomenon occurs among species found at high elevations, among others found in arid or desert regions, and in some cases in the female sex only, the male being winged and the female wingless.
The wingless forms in question are always allied to winged forms, and there is every reason to believe that they have been really derived from winged forms. There are also insects (fleas, &c.) in which metamorphosis of a " complete " character exists, though the insects never develop wings.
We have undoubted fossil evidence that winged insects lived in the Devonian and became numerous in the Carboniferous period.
As shown by the number and variety of species, the Orthoptera are the most dominant order of this group. Eminently terrestrial in habit, the differentiation of their fore-wings and hindwings can be traced from Carboniferous, isopteroid ancestors through intermediate Mesozoic forms. The Plecoptera resemble the Ephemeroptera and Odonata in the aquatic habits of their larvae, and by the occasional presence of tufted thoracic gills in the imago exhibit an aquatic character unknown in any other winged insects.
In addition to the appliances mentioned the tools comprise reamers to enlarge the bore of the well, the winged-substitute which is fitted above the bit to prevent it from glancing off, and above the round reamer to keep it in place, a temper-screw with clamps and wrenches.
Of wings, "a winged creature," and in the plural, b.
In height, decorated on the outside with beautiful reliefs representing a number of winged Victories engaged in the worship of Athena.
Aello and Ocypete, daughters of Thaumas and Electra, winged goddesses with beautiful locks, swifter than winds and birds in their flight, and their domain is the air.
14 gives a representation of the winged Harpies.
But when the legend became common property, other and better-known heroes were added to their number - Orpheus, Castor and Polydeuces (Pollux), Zetes and Calais, the winged sons of Boreas, Meleager, Theseus, Heracles.
This was done by the winged sons of Boreas, and Phineus now told them their course, and that the way to pass through the Symplegades or Cyanean rocks - two cliffs which moved on their bases and crushed whatever sought to pass - was first to fly a pigeon through, and when the cliffs, having closed on the pigeon, began to retire to each side, to row the "Argo" swiftly through.
There are three distinct and large thoracic segments, whereof the prothorax is narrower than the others; the legs are much shorter and stouter than in the winged insect, with monomerous tarsi terminated by a single claw.
When the aquatic insect has reached its full growth it emerges from the water or seeks its surface; the thorax splits down the back and the winged form appears.
This final moult is effected soon after the insect's appearance in the winged form; the creature seeks a temporary resting-place, the pellicle splits down the back, and the now perfect insect comes forth, often differing very greatly in colours and markings from the condition in which it was only a few moments before.
In her right hand was a Nike or winged victory, while her left held a spear, which rested on a shield on which were represented the battles of the Amazons with the giants.
Bellerophon is said to have returned to Tiryns and avenged himself on Anteia: he persuaded her to fly with him on his winged horse, and then flung her into the sea near the island of Melos (Schol.
Both are connected with the sun-god Helios and with the sea-god Poseidon, the symbol of the union being the winged horse Pegasus.
Many specimens exist of German winged and enamelled glasses of Venetian character.
At Jerablus, Sakhchegeuzu, Euyuk, Arslan Tepe, &c. Columns, probably of wood, rested on bases carved as winged lions.
Here it undergoes its fifth and last moult, and appears as a winged female, capable of reproducing parthenogenetically.
Sub-orders, but an interesting peculiarity of the Hemiptera is the occasional presence of winged and wingless races of the same species.
In many of these insects, while most individuals of the species are wingless, winged specimens are now and then met with.
The Heteroptera can be traced back farther than any other winged insects if the fossil Protocimex silurica Moberg, from the Ordovician slates of Sweden is rightly regarded as the wing of a bug.
1, C, D) are well developed, being adapted, as in the more lowly winged in,ects,such as the Orthoptera, for biting.
They are remarkable in having wingless males and winged females.
The ants which form this group are readily distinguished by the differentiation of the females into winged " queens" and wingless " workers."
The Vespidae or social wasps have " queens " and " workers " like the ants, but both these forms of female are winged; the claws on their feet are simple.
In the other families both sexes are winged, and the instinct and industry of the females are among the most wonderful in the Hymenoptera.
It is a very heterogeneous group, being fleshy-stemmed with a woody axis, the branches being angular, winged, flattened or cylindrical, and the flowers small, short-tubed, succeeded by small, round, peashaped berries.
Next come the various kinds of inhumation graves, the most important of which are rock-hewn chambers, many of which contain well-preserved paintings of various periods; some show close kinship to archaic Greek art, while others are more recent, and one, the Grotta del Tifone (so called from the typhons, or winged genii of death, represented) in which Latin as well as Etruscan inscriptions appear, belongs perhaps to the middle of the 4th century B.C. Fine sarcophagi from these tombs, some showing traces of painting, are preserved in the municipal museum, and also numerous fine Greek vases, bronzes and other objects.
