SCALE-WINGED INSECTS 



wings, thick, tapering bodies, and the antennae 

 thickest in the middle. The pink, greenish- 

 striped ELEPHANT HAWK-MOTH (see page 718) 

 is a comparatively small species. The speci- 

 mens measure about 2| inches across the wings. 

 Some species are much larger. The DEATH'S- 

 HEAD HAWK-MOTH, whose caterpillar feeds on 

 potato-leaves, is 5 or 6 inches in expanse ; and 

 some of the South American species measure 

 as much as 9 inches. The caterpillars of the 

 hawk-moths are generally green, often with 

 oblique lines of a different colour on the sides. 

 They are not hairy, though the skin is some- 

 times rough, and there is a fleshy appendage, 

 called a " horn," on the back, just before the 

 extremity of the body. The brown pupae 

 are found in cells in the ground.

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 com- 

 mon accident with swallow- 

 tailed butterflies and moths. 

 We may also notice the round 



is a smooth, 



whitish caterpillar, about 2 inches long, with a horn. It is 

 often reared in England on lettuce. The moth is a sluggish, 

 stout-bodied insect. It is whitish, with two dusky stripes on the 

 fore wings. The pupa is enclosed in an oval whitish or yellow 

 cocoon of pure silk. 



The EMPEROR-MOTHS, of which there is only one species 

 in England, likewise spin large cocoons, sometimes used for
