He who says Midge says Fly, Dipteron, two-winged insect; and our friend has four wings, one and all adapted for flying. By virtue of this characteristic and others no less important, she belongs to the order of Hymenoptera. Our Midge, the Microgaster, is the size of an average Gnat. She measures 3 or 4 millimetres. In spite of this likeness, they are easily distinguished.
Such a process is unknown outside the class of insects, and inside that class it is only known in a few of the two-winged flies. Now, how "Natural Selection," or any "laws of correlation," can account for the gradual development of such an exceptional process of development so extremely divergent from that of other insects seems nothing less than inconceivable. Mr.
'That is exactly the man for us; he is neither two-winged nor four-legged, so he will be quite safe. "They flew down at once to the rat-catcher and made their proposition. He laughed softly and pleasantly to himself, and accepted their invitation without any demur, and started at once with a light step and lighter heart for Hencastle.
The exhumation of the antique had, as we have seen, been contemporaneous with the birth of painting; nay, the study of the remains of antique sculpture had, in contributing to form Niccolò Pisano, indirectly helped to form Giotto; the very painter of the Triumph of Death had inserted into his terrible fresco two-winged genii, upholding a scroll, copied without any alteration from some coarse Roman sarcophagus, in which they may have sustained the usual Dis Manibus Sacrum.
There are a considerable number of Diptera, or two-winged flies, that closely resemble wasps and bees, and no doubt derive much benefit from the wholesome dread which those insects excite.
On close examination, they are seen to be minute two-winged insects, with dark coloured body and pale legs and wings, the latter closed lengthwise over the back. They alight imperceptibly, and squatting close, fall at once to work; stretching forward their long front legs, which are in constant motion and seem to act as feelers, and then applying their short, broad snouts to the skin.
Seemingly confident in their less complicated wing machinery, the two-winged fly rarely sought escape until within very close range of his enemy, and his resources never seemed to disappoint him at the critical moment. Among the insect assemblage was a large number of ants of all kinds and sizes, the common large black species being conspicuous. Here is one creeping and sipping along a grass stem.
Beneath the tapers on the outside is a bull with six wings on a starred background, and on the other side an angel, also with six wings, with two palms below, and two little two-winged trumpeting angels in the top corners, on a similarly starred ground. These three sides have a band of lattice-work at the base; the front has a panel with zigzag lines.
Only one group remained unaffected by the intense drought; the Diptera, or two-winged flies, continued as plentifully as ever, and on these I was almost compelled to concentrate my attention for a week or two, by which means I increased my collection of that Order to about two hundred species.
Nor is insect-life suspended at this season to the extent that a careless observer might suppose. A sunny, sheltered nook, at any time during the winter, will show you a variety of two-winged flies, and several species of spiders, often in considerable abundance, and as brisk as ever.
