I took an iPhone pic of the gathering in one of the bedrooms but it is not very clear.  Problem is that they only come out at night.  Turning on the light tends to start a flurry.  During the day they hide (probably from birds to an extent) in crevices which is how they usually get accidentally directed into houses (hiding in window cracks, door jams, and any other place that may lead indoors).

No, they're ugly brown all over.  They rarely sit about with their wings unfolded - mainly when dead. :)  They have a bifold so the wings drape back over the body (camouflage mechanism so they're not seen on trees I suspect).

Antennae are just like wings, arms, legs.
