If you used the words "bug" and "insect" interchangeably, you'd be wrong. Scientifically speaking, how do insects and bugs differ?

Strictly speaking, "bugs" are an order of insects called Hemiptera. These "true bugs," as entomologists also call them, are distinguished for having hypodermic-needle-like mouthparts. They're used for piercing into tissue to slurp up fluids.
