Help! Aphids?

Help! Aphids?

I have a oncidium (dancing lady orchid) that is just finishing blooming. The plant itself is untouched, but there are these bugs (I think aphids but they are black) on some of the dying and living blooms! How they got there is a complete mystery because it is an indoor plant. Should I just cut the branch off that they are on? Its at the complete edge of the spike. Should I bother with trying to kill them or just get them out of here? Thanks in advance. Here is the infestation Photobucket Photobucket And a picture, because I can't resist showing my baby off, from when it first started blooming in December :) Photobucket
