A scarab beetle grub from Australia. The C-shaped larvae, called grubs, are pale yellow or white. Most adult beetles are nocturnal, although the flower chafers and many leaf chafers are active during the day. The grubs mostly live underground or under debris, so are not exposed to sunlight.
The fly larvae feed on the beetle grub in the ground and pupate in the grub cell where they stay over the winter. [4] Wasps in numerous families, including Pelecinidae, Scoliidae, and Tiphiidae, are parasitoids of Phyllophaga grubs. A variety of amphibians, some small mammals, including skunks and moles, feed on the grubs.
The grubs hatch by late July. The grub population consists mainly of first instars in early- to mid-August, second instars by early September, and third instars by mid-September to early October. In frost zones, the grubs feed until November, then move deeper into the soil. In frost-free areas, the larva will feed all winter.
The witchetty grub (also spelled witchety grub or witjuti grub [1]) is a term used in Australia for the large, white, wood-eating larvae of several moths.In particular, it applies to the larvae of the cossid moth Endoxyla leucomochla, which feeds on the roots of the witchetty bush (after which the grubs are named) that is widespread throughout the Northern Territory and also typically found in ...
The grubs develop in the earth for three to four years, in colder climates even five years, and grow continually to a size of about 4–5 cm, before they pupate in early autumn and develop into an adult cockchafer in six weeks. [6] The cockchafer overwinters in the earth at depths between 20 and 100 cm. They work their way to the surface only ...
