If you would like to find out more about springtail, check it out here on Wikipedia.
I've shot springtail before but only when they came into the frame when i was shooting something else, like when shooting an ant. :D
This one was 2mm long excluding the antennae. To be honest, I lost it when attempting the high mag shots. I had to zoom out to 1:1 again on my MP-E65 to re-position my lens and zoom in again slowly from there.
this is how it looked like at 1:1 :D. I wouldn't have seen it if it wasn't moving at that time. But it did settle down for me to shoot.
It's been IDed as Collembola: Paronellinae by Frans.

All images were shot with a Canon 40D, Canon MPE65 1X-5X Macro Lens and Canon MT24EX Twin Flash.
