beetle larvae, known generically as
white curl grub (or cockchafer in
southern states), are a serious pest
of lawns. The signs of infestation
are easily confused with other pests,
diseases and disorders in turf and
present as a generalised yellowing,
then browning, followed by the death
of lawn.
White curl grub or cockchafer are
sometimes incorrectly referred to
as ‘lawn grub’ and ‘witchety
grub’. ‘Lawn grub’
is a colloquial term for surface dwelling
caterpillars such as sod webworm,
army worm and cutworm, which become
moths. The true witchety grub is the
wood-feeding larva of two families
of giant Australian moth

pest characteristics, host range,
