The antennea of a moth is fluffy like a feather. Moths don't like day light. That is why you will find lots of them flying around a porch light at night. Spiders aren't insects, but we learned about them, anyway. Spiders have eight legs and they don't have any antennae.
Spiders only have two parts to their body.
Some spiders live in a web and some don't. If you would like to see some great pictures of insects, provided by The University of Nebraska at Lincoln Entomology Department, click here .
