"What is worse than finding a worm in a apple?", asks the children's riddle. The reply: "Finding half a worm!"

The "worm" in question is likely to be the caterpillar of the Codlin Moth, (also spelled Codling Moth). Sometimes almost every apple or pear in an orchard will harbour one of these in a frassy mess in the middle of the fruit. When the caterpillar is full grown, it leaves the apple and pupates in a loose cocoon among debris on the ground or in the bark of a tree, where it spends the winter. The moth that emerges is surprisingly beautiful. When viewed at the right angle in bright sunlight, the brownish patch near the end of the wing shines with a striking golden sheen. I tried several times to catch this on film, but never seemed to find the right angle to show this off.
