Bugs and


beetles


The word “bug” is often used to


mean any creepy-crawly, but it is


actually an order of a particular kind of


insect. This order is called Hemiptera, and it has


82,000 species. Beetles are not the same as bugs:


they have their own order, Coleoptera. There are


370,000 beetle species—that’s one-third of all


known insect species.
