Looks like a thrip to me (but haven't gotten them personally). They can be real bastards, but not as bad as spider mites to deal with. They will eat/damage leaves so I would start killing them asap. They can lay eggs in leaf tissue as well making egg removal difficult for pest management, and only some sprays effective at getting rid of the eggs. If you don't want to use soap sprays, you can immediately combat them with water spraying at a decent pressure (eg. In the shower) or vacuuming them up every day to reduce their population and hopefully kill them off if you are diligent. Hope that helps!
