In a hem- lock-yellow birch forest in Michigan, mites and springtails were over twice as numerous in winter as in summer (Wallwork 1959). There are two main groups of annelids in the soil, the large red earthworms, Lumbricidae and Mega- scolecidae, and the small, whitish potworms, Enchy- traeidae. In rich, moist, humus soil, the red annelids may reach populations of over one hundred individ- uals per square meter; potworms sometimes occur in hundreds of thousands per square meter. Earth- worms ingest particles of mixed humus and mineral soil, absorb the organic matter out of them, and defecate around the entrances to and along the length of their burrows. Potworms feed more on plant and animal detritus, but may ingest some mineral parti- cles. Potworms may also exert some control over parasitic nematodes of plant roots (Kiihnelt 1950, Jacot 1940). Minimum numbers in Wales occur in late winter, maximum numbers in the early summer, and the biomass varies concomitantly from g/nr (O'Connor 1957).
