Yellow Shell Moth

The wingspan is 20–25 mm. The color of the forewings and hindwings is yellow to ochre brown (occasionally light). The forewings and hindwings are covered with brown or white serrated crossbars. There are usually three or four distinct white crossbars, which may be bordered by a black line. The wing margin is black and wavy. The yellowish eggs are round, only slightly flattened at the pole. The surface shows a large mesh. There are warts on the intersections. The caterpillars are greenish to slightly brownish with obvious segment incisions. The dorsal line is darker than the body color. The lateral line, on the other hand, is often brighter. The head is usually light brown and relatively small. The pupa is reddish brown with a short cremaster, consisting of two small bristles. The thoracic area and the wings have a brownish-greenish hue.
