. An introduction to zoology, with directions for practical work (invertebrates). 236 INTRODUCTION TO ZOOLOGY rolling Moths (Tortricidae) Fig. 164.—The Green Tortrix Moth. It is greenish or yellowish in colour, with a row of stiff tussocks of hair along its back; these are yellow on segments four to seven, with a red tuft on segment eleven. The Leaf- '^^^ Tortrix Moths are very small, dully coloured forms, the front wings usually with characteristic markings in each species, the hind wings greyish and without markings. Their larval habits are peculiar. Many of them live protected by the leaves on which they feed, rolling them up in various ways and binding them with silk. The Green Tortrix (T. viridana), which comes out in May, is very common. The caterpillar is green, with black warts on it, each wart bearing a hair. It is very commonly found on oaks, dropping by a thread from the boughs if shaken, and it often does a great deal of damage. The pupal stage is passed through protected by the rolled leaf. The moth (Fig. 164) which emerges has greenish front wings with a white fringe, and pale-brown hind wings with a grey fringe. The under side of all four wings is a silvery white. When at rest, the wings are held sloping obliquely to each other like a roof. Other members of the family live inside seeds, fruits, or buds. One is the cause of the destruction of many of our peas, the caterpillars eating their way into the pods and destroying their contents. They pupate in the soil for the winter, and should then be carefully destroyed by deep hoeing and digging. The Tineidae in- clude the smallest of all the moths and some of the most destructive, belong the little brown moths that lay their eggs on woollen materials and furs, the larvae of which work at times such havoc in our clothes by actually eating away the stuff (Fig. 165). There is the Clothes or Tapestry Moth (Tinea (Triclwphaga) tapetzella), which spins webs in Clothes Moths. Leaf- Miners. Small Ermines. (Tine
