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?
Hazmat,
Fly charts refer to when and which adult flies are hatching. So use the appropriate dries and nymphs that imitate these bugs that will be hatching at that time.

Hazmat,
The Early Black Stonefly is a dry fly too. You can find recipes in the fly archives on FAOL. There are also patterns on FAOL for the nymphs which are often very effective too since they are very active prior to the hatch. They crawl over to the shore or up onto rocks before they “hatch” into adults. Since they’re stone flies there are no emerger or spinner stages to worry about. For these look for simple flying recipes, not the ultrarealistic ones.
Check out the Entomology section on FAOL for more info on each of the hatches for tips on emergence, how to fish the different hatches, types of water for each etc.
