Earthworms and Light
Name: Karen Lee
Why are earthworms attracted to sunlight?
I don't believe they are. Earthworms are frequently on the surface after

Actually, earthworms avoid light. They'd be eaten if they were exposed during
the day. At night, they are stunned by a strong light. It is not within their
behaviors to deal with a change of light at that speed.
