Last year, along with the drought, there were a lot of trees in the Lungau that were infested with caterpillars. They form nests, strip the tree and then I daresay make a cocoon somewhere. Yet, I certainly didn’t notice many more moths mooching about last autumn. However, there are even more affected trees this summer and they show up so much now that all the trees are in leaf.
Quite ghostly with the horrible nests and cobwebs they make, even turning the bark white. I suppose, like the plague of flies in our attic, they’re a result of the relatively mild winter. Lets hope this winter is a really cold one and kills the little b*§$&ers off!
It’s called the winter moth. Apparently the males abound in the autumn, but the females are flightless or near so, and once mated lay the eggs in the bark of the tree, and once they hatch, the caterpillars are chewing away, sometimes before the leaf emerges. The tree will recover, even putting a second show of leaf on.
These ones in the picture below have started munching on grass, that could be a problem!
