The Swallow-tailed Moth (Ourapieryx sambucaria) is a common, large example of the Geometridae. The eggs are laid in July, usually on ivy leaves, and the caterpillars so strongly resemble little pieces of stick, that it is quite difficult to detect them amongst the ivy twigs. They hold to the twig by their abdominal feet only, the rest of the body being held stiffly out at an angle to the twig, so that it looks like a side branch. The caterpillars feed on ivy, hawthorn, or other plants, from August of one year until the following June, and then they pupate. The moth emerges in July. It is a large yellowish form, with two thin darker marks across the front wings, and a distinct " tail" on the outer margin of each hind wing, with a small dark speck just at the base of each such tail (Fig. 161). The Magpie Moth (Abraxas grossulariata) is another very common Geometrid. It is the caterpillar of this moth which often destroys to a serious extent the foliage of currant and gooseberry bushes. Both caterpillar and moth have a varied coloration of yellow, white, and black. The pupae also are conspicuous, for they are black and shiny, and barred with bright yellow. They are to be found attached to the bushes by a few silk threads. The China '^^^ China Mark Moths are worthy of mention Mark Moths because of the adaptation of the larvae to aquatic (Hydro- life^ which is rare amongst Lepidoptera. The c pmae;. caterpillars live on the surface of the water, and surround themselves with cases made of leaves in the fashion of some caddis worms. Fig. 162 represents the Small China Mark (Cataclysta lemnata), the caterpillar of which makes for itself a case of duckweed bound together with silk. The eggs of this moth are frequently to be found on the under surface of the leaves of fro
