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.
Everything is useful, no matter what size, including stick bugs. They bring happiness to their owners hearts, and if they are in the wild, they probably provide food to other animals. I'm sure there are more reasons why they are useful, but those are all I know. Stick bugs are very friendly, they cannot harm any humans or other animals, but I'm not sure about smaller insects. Only some species of stick bugs fight with eachother, but it is not common.
stick bugs are not endangered from my knowledge, only the giant stick bug is.
There are lots that are threatened like the Lord Howe Island Stick Insect.
Not most of them.
No, they don't bite or anything!

Yes, stick insects are insects.
Yes, stick insects are insects.
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).
they have no particular name,they are called non harmful insects
The changes talking place in our surroundings and which are useful to us are called Useful changes. The changes which are not useful but harmful are called Harmful changes
Yes. Stick insects obviously are insects, and all insects are arthropods! ^^
because they are camoflage and it is hard to see the stick insects. because they are camoflage and it is hard to see the stick insects.
