Summary

At least ten species of mites occur in Victoria Land, 9 in the north and 3 in the south; 2 species are common to both areas, or are even more widely distributed. Seven species belong to the Prostigmata, or trombidiform mites, and only one to the Cryptostigmata, or oribatid mites. No free-living Mesostigmata are known from Victoria Land. Most of the Prostigmata feed upon algae and are rather active mites, while the single oribatid feeds on fruticose lichens and is very slow-moving. The mites occur rather widely under stones, even where no macroscopic vegetation is visible, but are found in greatest numbers among algae. By far the largest populations were found among algae growing on feathers on the lower parts of long-dead penguins, particularly under the wings. Thousands of eggs were found on the belly feathers, and also under rocks and in cracks in soil rich in decomposed birds, feathers, and guano.
