It's easy to watch bugs all day long -- especially when you make them yourself. Create your own insects out of natural materials and pose them around your campsite. You'll find some suggested bugs below, but feel free to use your imagination to come up with others too.
First, build a body from the pebbles. For example, make a dragonfly by gluing a small rock (the head) on top of a long skinny rock (the body). Or glue three small pebbles end to end to make an ant.
Add appendages by putting a drop of glue on the end of each leg, then pressing it to the rock. Finally, glue on wings and antennae, if you like.
