It looks like some kind of artery, but I really have no idea. I'll wait till someone guesses. :)

Ferry is correct, didn't take him very long. Next one will definitely have to be more difficult.

Mitch had the right idea, they are arteries in the sense that they are transportation corridors, but instead of blood they they transport air to every cell. Some think that this breathing system is the factor that limits the size of insects. Some very ancient (fossil) insects were much larger, made possible by the higher concentration of oxygen in the air.

Well, the next obvious question is, how did you isolate it to get pics of it? It looks like some delicate surgery would be needed. A transplant maybe? :)

These things are reasonably tough and flexible.
