Looks like glue or tape on the wing.
I answered you about it in previous post. The mere fact that your are repeating your question means that you are a troll.

I am reposting an earlier post of mine
in another thread so that some of the questions which are being repeated here are answered:
Looks like skeptics never die. Why is it so hard to accept the truth?
Iranians have been saying the truth from day one. These pictures prove they have developed a new kind of technology in air defense field. A technology making it possible to take over the drones.
Some observations:
1- Drone is painted in light desert color. Most probably because it was being used during the day which explains lighter color against a bright sky line and also that fighters flying above it would have difficulty spotting it against a desert background. This means the drone was being used to make high resolution photos and videos in day light in addition to other sensors on board.
2- The drone is actually stealth, since the shape is almost a copy of B-2 and there are not much metal visible. All composite plastics. The other thing to note is the drones' assembly which seems to be modular maybe for ease of transportation to battle fields a far. Most probably wings come off completely and there would be three main sections when they transport it into and out of Afghanistan aboard a C-130 perhaps. It is clear also that Iranians have disassembled the plane and have just re-assembled it for this video as can be seen from the joints on the wings.
3- Iranians have probably removed all thing inside it before filming it. Engine, electronics, landing gear, everything. It is probably just the hull there. Nothing more and is empty inside. This could have been done to learn more or for security reasons because they wanted to find out if there were explosive charges inside this. The job must have been done by bomb disposal units in addition to aeronautical engineers. That is why they are not showing engine outlet and undercarriage since there is nothing much there and every thing has been removed including sensors. Iran is known to keep anything of value in pieces in different corners of country far away from each other to minimize effect of an air strike.
4- Drone is in exceptional shape except for a few dents which are repairable. If properly fitted and repaired it can probably fly again. This goes to show, it never crashed and probably landed in a proper airport. Implications are clear. Iranians were right when they were saying they had hacked it and had control over it. This was probably the work of a super virus in retaliation for Stuxnet. Welcome to the age of cyber warfare.
5- Iran should not divulge any technical info whatsoever, what they have shown is already too much. Iran should exchange this technology with technology and not with money since Iran already has money. They should exchange the technology in this drone with S-400 technology, anti-ship missiles technology and some high tech radars technology from Russia. Not less. Iran should receive technology so that they can build those things for themselves and not depend on Russia for the supply. It is actually worth more. In any case drone should stay in Iran and any reverse engineering by Russians should happen in Iran along with Iranian engineers.
6- Iran should report this incident to UN for official purposes and protest against violation of its sovereign air space. Regardless of the outcome, Iran will have the moral superiority.
