My take on a Dragon/Spider hybrid.

Their webs come from their mouths (I feel like I have to specify that)
They are usually born without wings but are able to make web wings connected to the spikes on their backs.
They have six eyes but four of them are closed in this one. They can see and thrive in the dark
They can stick to walls
They do have a Queen that is bigger then all the rest and can command them all
