Fruit flys
The fruit fly that was sent into space was named Drosophila melanogaster.
For the same reason frogs hop. That's what they do. Actually, they are similar to a mosquito, and want blood, so they bite.
Fruit flys need air to breath like many other insects.
fruit flys are attracted to about every scource of food mostly sugary fruit

fruit flys and other regular insects
tigers of sumatra and dead fruit flys, everywhere.
I am assuming you mean 'Why are fruit flys used in experiments and not humans?' in which case the answer is there are so many fruit flies and they are not really neccicary to us humans. Also if something goes wrong, humans could die or get mentally ill. Fruit flys just croak over and aren't missed. Correct me if I am wrong please.
