Ordinarily the way this is done is to skeletonize them, that is to say, to carve away all but the bare minimum of metal. |
They skeletonize the leaves by rasping away the green part of the leaves, then make holes in the leaf. |
The larvae skeletonize the foliage, but feeding damage is not conspicuous at this stage. |
The larvae skeletonize leaves in May and June, starting from the bottom of the plant and working their way up, and the adults finish up any leftovers from July to October. |
At middle depths of the forest floor, small invertebrates, especially dipteran larvae, partially consume or skeletonize leaf litter before emerging as adults. |
How fast the bugs skeletonize a carcass depends on how high the colony is. |
