It emerges in April. Hand-picking is best for these conspicuous caterpillars, as they soon make their presence known. The trees may also be shaken over a sticky board, and the insects afterwards picked up and destroyed. With hairy caterpillars it is a well-known fact that the gardener gets very little help from the usual bird-dwellers. The chief exception, so far as the writer knows, is in the case of the cuckoo, which seems to have a particular relish for such hairy creatures. One other species of moth should also be mentioned, as its food-plant is entirely the Rose. This is Cidaria fulvata^ another very common species. The caterpillar emerges in April, but is not readily seen, as its colour harmonises so well with its environ- ment. In colour it is pale green, with greenish-grey lines upon the back, and yellowish near the spiracles. Hand-picking is the only remedy. Even more destructive than the moth caterpillars are those of the Sawflies feeding upon the Rose. Those generally seen feed exposed, though there is one species occasionally met with i^Pamphiliiis i?ianitd) which encloses itself in a case fashioned from its food-plant. There is a large number of the Sawfly Caterpillars, but amongst the commonest and most destructive are Hvlotoma rosa (Fig. 63),. Fig. 63.—Larv^ of Rose-leaf Sawfly. a bluish-green insect with a black head. The eggs are laid in the Rose-twigs in a double row, each egg being deposited sepa- rately. To add to the gardener's trouble, the insect is double- brooded. When the larvae hatch out, they at once commence.
