Abstract:

Glacicavicola bathyscioides Westcott beetles were kept in laboratory culture. Indirect evidence suggests that the beetles in culture fed on arthropod remains. Of 52 individuals, eight still were alive two years after capture. They may live, in nature, at least 3 years as adults. Immature stages are not known. Some of the caves in which the beetle is presently known to occur probably were occupied less than 2,000 years ago. Their present range, 186 km maximum diameter, was attained during the Wisconsinan glaciation by overland dispersal.
