All insects serve a purpose in their lifecycles, they need each other and we need them to eat some insects we don't like. A cockroach is the cleanest insect on earth. Not that I want to live with any.l

I agree with "Year of the Monkey" but I fail to see how this question belongs in the Infectious Disease category.

Dragonflies...They eat mosquitos which carry west-nile and since I live in Minnesota land of 10,000 mosquitos I love dragonflies!!!
Bees...Even though they can sting they pollenate and help our plant life reproduce, and make honey

Gosh....this sounds like a homework question.
How are you going to learn anything if you don't look it up YOURSELF. And this isn't a medical question. Use the right category.

Bees make honey, and pollinate flowers and other plants, and spiders eat pests like flies, and scare little kids.
All useful things.
