Unidentified Eggs and Egg Cases

This is the section where images of unidentified eggs are kept, with the hope that someone will figure out what they are eventually.

In addition to noting the size when submitting unidentified egg photos, please record any clues about the context in which you found them: Near water? Under a rock? On the wall of a house by a porch light? If they're on a plant, always record the plant species, or if you're not sure, submit photos of the leaves, flowers, fruit, etc. so someone can identify them.
