I found these cute bug boxes at Art Things, our local art store, a few days ago. I thought the kids would enjoy them as they are very interested in bugs and worms. After about and hour or so they had caught their first bug. A stink bug. Next was a spider.
After close observation, they decided that the stink bug had passed so they thought, "Perfect! A meal for the spider." It was fascinating to watch the spider wrap the stink bug in a web for a later snack. This was definitely worth the $3 each for the boxes.
One bug down, one bug fed, time to hunt for another insect. It seems you don't have to go far to observe nature at it's best.
