COULD THEY EXIST IN SPACE?
Yes, insects require oxygen to survive. They do not breathe the same way humans breathe as they do not have lungs and do not need to circulate oxygen through a circulatory system like humans do. Instead, they have a tracheal system which is comprised of a series of tubes. These tubes carry the oxygen through the body and they release carbon dioxide through a gas exchange process. For this reason, as well as their need for habitat and finding food, insects could not survive in outer space.
