Were the first cockroaches winged or wingless?

[Keith]

And did a wingless species like Hissers at one point in time have wings, or were they always wingless? The thought of a flying hisser is so cool!

Whatever this species is, it most resembles a hissing roach with wings, awesome!

 

[Nicolas Rousseaux]

I think the loss of the wings is an evolution, and that they were firstly winged... But did robably not look like the hissers we know nowadays!

If you look closer to the thorax, you can see what I think to be the remains of the wings, like on a nymph

It doesn't mention wings, but who knows.

Any sources to cockroach ancestry would be a nice share.
