My brothers used to like to collect insects and other little creatures in nature when we were growing up. One of them tried to collect grasshoppers, bees and butterflies. He would get a big jar, poke holes in the lid of it so the insects could breathe, then put them in the jar.
I would look at all the pretty butterflies he collected and admire the assortment. But, of course, most of them didn't survive for more than a day in that stuffy jar.
