Aphids?

[zxyqu]

These little buggers just decided to perk their heads up on some of my mounts . I think they're aphids, but as the is my first orchid pest, I'm trying to confirm before I carpet bomb them. Thoughts?

Also, these little guys range from large (like the one here) to miniscule. The big ones may be roughly 1/16" long, maybe. Basically these pricks are tiny!
