A Case of Late Breeding in the Mole Mogera kobeae and Its Nest

The presence of the mushroom Hebeloma radicosum, which grows specifically on mole latrines, led to the discovery in the montane area of Kyoto in October 1984, of a mole nest and a case of unusually late breeding in Japanese Talpinae. The nest was excavated near the latrines under the mushroom, and three juvenile Mogera kobeae were collected in and around the nest. These moles presumably belonged to the same litter, aged between four and six weeks old, and appeared to be almost ready for natal dispersal. This is the first published report of talpine moles at such a developmental stage being collected in autumn, in Japan, at their own nesting site. These juveniles might have been the result of delayed breeding but not a second litter, as the early part of that year, i. e. the moles normal breeding season, was unusually cold. The nest and its surrounding features are also described.
