A mass occurrence of a parasitic blow fly, Melinda pusilla (Villeneuve, 1927), was annually observed during winter (November to March) in a modern big building of Yokosuka Electrical Communication Laboratory, Nippon Telegraph and Telephone Public Corporation soon after the laboratory was built on a forested hill top located in the Miura Peninsular, Kanagawa Pref. The adult flies were mainly aggregated on the combined first and second floors (1+2F) of this tall building where they entered the laboratory rooms and were a considerable nuisance. Studies were made from November 1983 to March 1984 on the number of attracted flies, the route of migration and entrance into the building, and the behavior of hibernation. The flies were unmated and were found hibernating throughout the building. However, distinct daily patterns of aggregation and movement were observed. The number of individuals increased from 11 : 00 to 13 : 00 on the outside surface of glass windows and walls, especially on the south surface of floors 1+2. In late afternoon the flies seemed to enter the eaves and rooms on the north side of floors 1+2 via small openings. Groups of 10-60 individuals were then found hibernating on the ceiling. These hibernation locations showed relatively lower air temperatures (6.0-17.5℃) and higher relative humidity (RH 22.7-50.0%) than those (9.5-22.8℃, RH 11.5-40.2%) in on the south side of the building during 13-19 December 1983. Reoccurrence of this fly problem was prevented in 1984 by sealing small openings on the north surface of the building with heat insulation foam. The life history during spring and summer and host of M. pusilla remain unknown except for the fact that copulation occurs in April.
