Scarab Beetle

The family Scarabaeidae beetles or scarabs or scarab beetles vary considerably in habits, with many species feeding on manure or on decomposing plant materials, others on growing roots or leaves, and a few on fungi. These beetles are one of the most popular families with insect collectors because of the large size and beautifully coloured, hard, highly polished forewings of many species. White grubs are larvae of scarab beetles (Scarabaeidae). White grubs are creamy white, medium to large, with a distinct brown head capsule, C-shaped body with prominent legs and a slightly enlarged abdomen. Scarabs have long life cycles, typically 1-4 years. Species that are potato pests cut roots and stems and make large, clean, shallow circular surface wounds in tubers. Infestations are usually worse when potatoes are planted in weedy fields or fields previously in sod. White grubs have become increasingly troublesome in Asia and Central America since the phasing out of chlorinated hydrocarbon insecticides. Major pest genera in India include Anomala spp. and Melolontha spp. In the Americas, Phyllophaga is the most economically important genus.
