Okay so the name isn't official but here are the smog, smoke, mist, reaper, or fog wings

Here's a terrible wing design (my roommate helped figure it out)
Close up

Okay next part.
Color- they normally come in greys, blacks, purples, dark blues, dark reds, dark brown, and dark greens.
Their wings are made of a gas. The gas disappears in the sunlight leaving them flightless in the day. Their spikes are made of a toxic gas that can kill a dragon when exposed to it for too long. They are surrounded by a mist like substance that disappears when exposed to sunlight. They live in a underground maze of tunnels under pyrrhia where sunlight doesn't reach. The tunnels are filled with fog and mist. They are nicknamed reaper wings due to them being spotted on battle fields the night after battles. They have no royal family but there still can only be a queen.

Queen: Queen Cloud

Ability's : they release a semi toxic gas instead of venom, frost breath, or fire. Few have the ability to completely surround themselves with fog in the battle field making it almost impossible to land a hit easily. Some also have the ability to create illusions with fog or mist. It is uncommon but some twins have the ability to light their gas on fire. (One twin releases the gas while the other lights it.)

Strengths: They attack at night while their Enemy's are sleeping.  They can create illusions and surround themselves with fog. They have poisonous spikes and  can chase there target out of hiding with the semi toxic gas. Night vision. They are immune to the gas of their own species.

Weaknesses: They are left flightless until darkness falls.  They are almost completely blind in light due to the fact that they only go out in night and are rarely exposed to light.
