Americans have a tendency to call all insects “bugs”. I first thought the terms were interchangeable, but I’ve learned that while all bugs are insects, not all insects are bugs.
The key difference between true bugs and other insects is their mouth parts. True bugs have rigid piercing/sucking mouthparts that look like a long beak and act like a straw. Most suck plant juices, but some feed on animals. Water bugs are venomous; they liquify then drink their prey. Yum!
