I've noticed a bunch of tiny white curly Q's on my LR and glass. They are extremely small and I couldn't get a quality picture. They look like this "@" actually, only all white. I noticed them on my LR a while back, but I thought they were the start of stony tubed featherdusters (just a guess I had??) which I already have a number of. But now there are a bunch, all different sizes on my glass and they are not stony tubes from what I see. Are the some type of pod?
