Seven myriapod species are recorded from 20 l samples taken from the upper and lower layers of two compost heaps of different ages in October and November, 1983, and February and April, 1984. The animals were extracted from the samples by hand. Data are given about the abundance of the species, sex ratio and seasonal distribution of different instars. Attention is paid to the ecological conditions of the compost heaps, which may be favourable places for hibernation of species sensitive to low winter temperatures.
