Some time back, I received this good advice:

I've seen dark, and it is really obvious, but what about cloudy?
Can the trachea be cloudy - and white?
Seems there is a range from perfectly clear to whitish that looks
normal to me. The whitish ones have a spiral design on them like a
vacuum cleaner (or bee blower) hose and branch.
Is the appearance of the tubes something that varies with the age of
the bee? Or am I seeing low levels or early levels of mites in the
bee when I see some opacity?
I realise that this really doesn't matter too much because if the
infestation is that questionable, I am not having to treat.
But I'm still curious.
