Or at all?
Do they even have lungs?

Insects don’t have lungs like you or me. Instead they have a tube system, which runs all over their body, and which carries air to all parts of the body. These tubes are called trachea. The air is carried to the body when the movement of the insect’s muscles pumps it there through openings in the insect’s skin.

Yes they do breathe oxygen, just not at all in the same way as we do. They have what is known as an open trachaeal or circulatory system, basically what this means is that there are no arteries and veins like in our bodies for the transport of oxygenated blood to various organs. They do not have lungs, they have small holes along their abdomen usually 8 pairs. These Spiracles as they are called are attached on the inside by a tracheal system. This branched trachaeal system works on passive diffusion. Oxygen is passively taken into the body (they do not inhale) and the trachaeal system passes the oxygenated air over capillary beds located all throughout the body. Insects therefore do not have a circulatory system for the transport of oxygenated blood. Also, because insects are not homeothermic and do not have high oxygen demands, they never had the need to have these much more specialized organs in their bodies. Some insects like honeybees for instance seem to be breathing, if you look closely at their adbomen when they are at rest, it is folding in and out like an accordian........so hey you never know maybe one day some insect somewhere may actually take a breath of fresh air!

Yes, insects breathe oxygen, just like you or I, however, they do it in a much different manner than we do. As previously mentioned, they do have a "tube system" of breathing. Air passes through spiracles, little openings along the sides of their bodies (usually 12-15 per side, one per segment) , after a muscle contraction, and into the tracheae. The tracheae branch off into trachioles, which are basically smaller tracheae, and after a few more branchings, the oxygen is delivered directly to the muscle tissue. This system is extremely effecient, and the main reason that insects never tire after strenuous activity, seeing as the muscle tissue is never deprived of oxygen.
Just a side note, though, while insects do not have lungs, most arachnids, especially spiders do in fact have them.

they have small pores in their abdominal part these pores are endings if tubes that run through their body they inhale air(OXYGEN) by expanding their abdomen and exhale by compressing their abdomen. and no animal can live with out oxygen and insect makes about 80% of the kingdom animala.

I have not yet assigned this subject to my survey team. So, you may have to wait for my answer.
