Harmful insects include aphids, whiteflies (eat our crops), mosquitos (carry disease), fleas and lice (suck blood). However, the insects that eat our crops mostly only do so because we practise too much monoculture and kill off their predators with insecticide. The herbivores such as aphids and whiteflies reproduce fast enough to build up resistance, whereas their predators such as ladybugs do not.
Useful insects include those ladybugs (eat aphids etc), parasitic wasps (kill many harmful insects), and bees (pollinate plants and make sure they can reproduce and bear fruit).

Heather had to collect insects for her biology project She was able to collect 126 total insects She collected 5 times as many insects that could fly as insects that couldn't fly. How many could fly?
Flying insects = f Non-flying insects = n n+f=126 f=5n n+5n=126 6n=126 n=21 non-flying insects f=5*21 = 105 flying insects
