I can't see anything there - but if it's IN the soil, it's probably a fungus gnat. Get some Mosquito Bits and follow the directions ... it works beautifully. Fungus gnats like constantly wet/moist soil so if that IS what this is, you're overwatering and inviting them in (AND doing damage to your plant!). Only water when the soil is completely dry - when you lift the pot, it should feel very VERY lightweight...
Good luck!
