[FONT=arial, helvetica, geneva][SIZE=-1]Springtails feed in the leaf litter on decaying plant matter, fungi, and bacteria helping to enrich the soil. [/SIZE][/FONT][FONT=arial, helvetica, geneva][SIZE=-1]Restricted to moist soil and litter conditions, springtails do not survive drought conditions. [/SIZE][/FONT]Because of the ease with which moisture can escape their bodies, springtails are extremely sensitive to drying out, and many species inhabit soil. It has been estimated that as many as 50,000 springtails can inhabit 1 cubic foot of organic topsoil. The soil contains sufficient moisture and food for springtails to survive. Their food includes decaying vegetation, fungi, bacteria, pollen, algae, lichens and insect feces. The feeding activities of springtails enrich the soil by breaking down these forms of organic matter and releasing the nutrients they contain. Because of these activities, springtails are considered to be a good indicator of soil health.
So all in all you dont have anything to worry about, your soil is healthy and they are going to add nutes. You should send me a couple of those bugs, lol!
