"bug" の定義と意味

What is "bug"?

The term "bug" is often used to refer to any small insect or creepy-crawly creature, but technically it has a more specific meaning. Bugs are a type of insect that belong to the order Hemiptera, which includes around 50,000 different species. Hemipterans have specialized mouthparts that allow them to pierce and suck fluids from plants and other organisms. Common examples of true bugs include stink bugs, bed bugs, and cicadas. However, in everyday language, the term "bug" is often used more broadly to refer to any small creepy-crawly creature, including insects, arachnids, and other invertebrates.
