Fruit Saucer

got some tiny white (3-4mm) white riggly/jumpy things on the saucer of my pot plant, any ideas? help please!?

have two plants (oranges grown from seed, though theyhave not fruited yet) recently repotted them, also have a recycling pot in he kitchen so we sometimes have a few fruit flies around, but recently noticed that both plants have some tiny wriggly things between the pot and saucer, they also dissapear quickly by jumping if disturbed!!! (very freaky) I looked on the web for fruit flies, but it says their larva are immoblie so im thinking I have two problems! any ideas on what they are and how to get rid of them????
Hany advice greatfully recieved!
Thank you!
thanks for the answers so far, I dont think they are white fly, ive seen that before, these do not have wings, they jump! and they are not on the plant or leaves they are hiding under the pot, also I am from england, if that helps!

These are white fly get a white fly killer from any garden center and mix as per instructions and spray simple as that
another is mix some soap and water and spray plant over
