Fig. 52.—A Sesiid, or clear-winged moth, Synanthedon pic- tipes: a, Moth; 6, eggs; c, caterpillar; <l. pupa; c, pupa in the "; Their larvae are large, smooth caterpillars, often with a horn near tip of body. The old group of Bombyces (fig. 49), now divided and scattered, included some of the largest species of the order. The pale green Luna moth and the American silkworm, or Cecropia moth, are well-known forms. The Io moth has a green caterpillar, which can "sting" when handled. The gipsy moth also belongs in this group, jM as well as the silkworm moth, which, next to the honey bee, is the most valuable insect. The caterpillars of this group are usually spiny or hairy. Allied are the Noctuida?, or owlet moths (fig. 50). They are rather stout- bodied, of moderate size, with dark colors. The caterpillars are CASE. smooth, and often known as cutworms. Among them are many of our most destructive insects, such as the bollworm and the cotton leaf-worm. Another great group is the Geometridse (fig. 51), whose larva? have fewer prolegs than usual, and in consequence hump up their body when crawling, and so are called measuring worms. The moths have slender bodies and large wings, often of handsome shades and. tints. The cankerworcn belongs to this group. The slug caterpillars, which apparently have no feet and are often of curious shapes and bright colors, are the young of the Limacodid moths. One of these, the saddle-back caterpil- lar (fig. 135), will ' 'sting" when touched, producing a sort of rash on the skin. The clear-winged, or Sesiid moths (fig. 52), are peculiar in that a part of the wings is destitute of scales. Their larv» usually bore in the stems of plants and trees. The caterpillars of a small group of moths (Psychidae) live in a case of leaves, which they carry about with them. One, the well-known bagworm (fig. 136), is often found upon evergreens, locust trees, etc. S
