[Note Guidelines] Photographer's Note
Those insects are 1.5 mm long. They don't look to become larger. The younger ones are totally white.
I see them everytime I water the plants. They are floating. They try to jump to escape. But in the next second they slide back to the place they were. They got free a few minutes later when the water disappear under the surface of the ground.

As the ground surface was too dark for a pic with an inverted lens, I filled up a 3 cm diameter glass with water and put the insect on top. Again after every tries to jump to escape, he would end up precisely in the middle of the glass where my lens was waiting for him. Enough light would come from the water filled up glass under him.
I didn't have a proper objective to invert, and couldn't get beter quality with that one (dark corners, and legs out of focus). Videos were much beter.

Update on 09 Jul 2006:
Thanks to Greg (red45) for the help on the ID. Greg knew those were collembolas. Being on the good track, I looked further for the ID. I think that this one might be Folsomia candida.

Hi Jean Marie!
I think this small insect belongs to Collembola. Nice supermacro, good use of inerted lens. Supermacrophotography of water beings is my favourite.

Collembola are primitive wingless insects in the subclass Apterygota. They are chiefly soil and/or litter dwellers, and live off the fungi that decompose organic matter. Like other insects, they have three body parts (head, thorax, and abdomen), three pairs of legs, and one pair of antenna. Unlike most insects, they have no wings at any stage. Instead they posses a forked "tail" called a furcula, which enables them to spring out of harm's way. Their common name - springtails, comes from this behavior. They are only a few mm long at the most, and rather hard to find. However, they usually occur in large groups and can be observed walking about if the top layer of leaf litter is carefully removed.

Hi JeanMarie,
I'm glad Greg knew what it was as I don't have a clue :-) An interesting shot and note, inventive camera work as well.
Regards,
Adrian
