I was walking under my white Birch tree and there's so many of these bugs on it that they're just falling off. What are they? There are also a lot of leaf miners (specific variety unidentified. This is the first year that I've seen so many leaf miners in general) on that tree. I didn't know if the leaf miners were the baby bugs or if the bugs were eating the miners.

This is an immature (not adult) life stage of an insect in the Order Hemiptera. It might be a Seed bug (Lygaeidae). This insect is unrelated to leafminers (who are often flies). As an adult, it will feed on the leaves.
