Abstract
The house longhorn beetle (Hylotrupes bajulus) is a wood borer whose larvae are pests in houses. Four Danish lofts were examined. Records were kept of temperatures, and of growth and metamorphosis of larvae in test blocks inserted in the rafters. The lofts with gray asbestos cement slate and with natural slate roofs were warmer in summer and cooler in winter than those with tile roofs. Larvae grew more rapidly in the warmer test blocks and pupation occurred earlier than in the cooler habitats. Denmark appears to be near the northern limit of distribution of the species and these findings may not apply to infestations in warmer macroclimates.
