Hey Trent and Michelle,
In my experience this pest has two forms, and may be two different pests. For me, they always appear together. There are the white dash things, and also the round scale-like things that really stick to the leaves. They may have some symbiotic relationship, are the same thing, or just like the same food, but they are always together, which I think is causing some of the confusion here. Until this confusion is really sorted out, I will refer to them as the Hawaiian Whitefly/Scale plague.
