Argentinian Scarab (Cyclocephala signaticollis)was first reported in Australia in the mid-1950s and has now spread through the ACT and NSW where it can cause significant turf damage. It has recently been found in Adelaide.
The adult beetle is very similar in size and shape to the better known African Black Beetle, but is coloured a mid-tan, with subtle striping on the wing carapaces. Beginning during December, the larvae start to feed and can cause considerable damage to grass, which can be accentuated by widespread feeding by birds and other predators. This activity generally increases in the autumn as the larvae get larger. In our trials larval numbers can be as high as 350 per square metre.
