Quick question.. I'm attempting to tie up a couple of boxes of flies for a couple of the places I like to fish.. so I googled up the hatch chart here:

I'm assuming these are all dry flies(with exception, perhaps for the little black stonefly) but am not sure since they all go through the various stages of life. Should one assume that a hatch chart is charting dry flies unless otherwise stated?
