These caterpillars have spent the past few days completely stripping a small wattle tree at the end of my carport. They live communally in a large web balls and leave the tree covered in web when they leave after consuming every single leaf.
This trail stretched over 9 metres in total and as each caterpillar is only around 10mm the count must have been well over a thousand individuals.
