I opened the bin to check on them with my hand lens, and also to harvest a little of the castings for a couple of small plants I've got going in my mini greenhouse. I found hundreds of strange, small white insects running around when I lifted up some of the castings, so of course I took a picture and then ran to my computer to see what I could find. A quick search led me to conclude I have white springtails in my wormbin.

"chew on decomposing plants, pollen, grains, and fungi and are beneficial organisms in the bin. They have been found to be beneficial because of their capacity to carry spores of mycorrhizal fungi and mycorrhiza-helper bacteria on their tegument, soil springtails play a positive role in the establishment of plant-fungal symbioses and thus are beneficial to agriculture. They also contribute to controlling plant fungal diseases through their active consumption of mycelia and spores of damping-off and pathogenic fungi."
Springtails don't harm the worms and are part of a normal, healthy wormbin. There are other kinds of springtails that are considered pests in agriculture, but these guys are worth keeping around.
Here is a cool video of springtails, courtesy of Cathy's Crawly Composters:
I also discovered lots of worm eggs. I know that means I'm going to have to start another bin soon or it will be too crowded.
