Moth trap

A moth trap is a device used by scientists or people who want to study moths or keep track of which types are in an area. It usually looks like a box with one or two bright lights inside. When moths fly close to the lights, they become attracted to the light and fly into the trap. The moths can then be studied or counted. It's like a little bug hotel for moths!
