How the distribution of invertebrates in a habitat depends on the light intensity?

Is this an assignment? You may have noticed that there are a few people on here who are all trying to answer the same question. It might be worth adding a note to their questions so that you can all discuss it together. Back to the question ... invertebrates make up something like 97% of all animal species. So the majority of animals are actually invertebrates. Here are some ideas. Think of some common examples and how they respond to light: moths are attracted to light, whereas worms, woodlice and the like are usually found in dark damp places (low light intensity). If an animal has poor eyesight, it generally won't want to hand around in the light where it might be eaten (predators are common). What are the things that make up a good habitat for an invertebrate? How is this affected by light?

Oh thanks
