Most people tend to call anything with lots of legs a "bug." However, to an entomologist, a "bug" is one of the 35,000 or so species of the order Hemiptera. Hemiptera means "half wing" and refers to the fact that part of the first pair of wings is toughened and hard, while the rest of the first pair and the second pair are membranous. Hemipterans also have modified piercing and sucking mouthparts; some suck plant juices and are plant pests, while others can bite painfully.
