SWALLOW-TAILED BUTTERFLY
The only British species of this butterfly is almost confined to the fen districts of Norfolk.
The Emperor-moths, of which there is only one species in England, likewise spin large cocoons, sometimes used for commercial purposes. The caterpillars are generally more or less spiny or tufted. Some of the moths have long tails on the hind wings, like swallow-tailed butterflies, and there are several species in South Europe, South Africa, the East Indies, and North America of a beautiful sea-green colour. It will be noticed that the specimens represented on page 718 have the tails a little broken, which is a very common accident with swallow-tailed butterflies and moths. We may also notice the round or crescent-shaped spots in the middle of the wings of some of the moths represented on this page and the next. These are very characteristic of the emperor-moths, and there is often a transparent spot in the centre of the concentric markings. Two other North American species of this family are shown in the photographs on page [719], rather under natural size. The second of these, the Cecropia Moth, is represented with its cocoon. This moth has occasionally been captured in England, having been introduced either accidentally or by design. A year or two ago a specimen was brought to the Natural History Museum at South Kensington which had been caught in the street close by. During the summer many foreign butterflies and moths may be seen alive in the Insect-house at the Zoological Gardens, Regent's Park, and several of the photographs given in these pages were taken from specimens living there in the summer of 1901. The largest of the emperor-moths is the great Atlas Moth of North India, the largest of all known butterflies or moths, which occasionally measures almost a foot across its reddish-tawny wings.
