yes and no... Most stick insects are very successful in the wild and in captivity. There are over 3,000 stick insects in the world. There are some, however, that are critically endangered, and others that have become extinct. The idea that because there are lots of species they aren't endangered is ridiculous. There are dozens of types of bear. that doesn't mean that no bears are endangered.

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).
