小知识
An insect is commonly called a bug. Flies, bees, and wasps are all insects.
Insects are the most numerous type of animals on Earth — and also some of the least popular. These tiny, air-breathing arthropods always seem to be where you don't want them. Mosquitoes, ants, and bees can ruin a picnic. Moths ruin clothes. Cockroaches are disgusting and extremely hard to kill. It's no wonder insects aren't as popular as cats or dogs.
