Caterpillars of the Oak Leafroller take cover using the leaves of the host plant they feed from.
The white and golden Oak Leafroller is covered in a mottled, almost mosaic pattern of golden or brown circles and lines. Some individuals are darker than others, but all have rounded 'shoulders' and large white circles on the lower part of the wings. They are often seen flying in deciduous forests where an ample supplies of host trees live.
Caterpillars feed on the leaves of maple, oak, buckthorn, witchhazel, and apple trees. They are hard to spot because they use their bodies and caterpillar silk to roll up a leaf in order to hide inside of it. This obscures them from the view of predators, but also gives them some protection from the elements. It helps that their bodies are a leafy, green color, too, so when looking inside a rolled up leaf, one might still overlook it.
