Seasonal food supply for the house spider, Achaearanea tepidariorum, was investigated from 1985 to 1986 on the campus of Hirosaki University, Aomori Prefecture. A total of 1490 animals caught by the spider were collected in the two years census and classified into 15 orders of arthropods, in which wingless animals predominated. The abundance of the wingless animals in the diets might be due to the web structure of this spider. Though the spiders fed at any time, more than half of the prey items were captured during the daytime (6 : 00-18 : 00). The seasonal food supply as inferred from the rate of predation shows an unimodal pattern with a peak in July. The result corresponded well with the seasonal trend of the number of possible prey animals collected by sticky traps in the same field. As this spider continues to reproduce over a long period of time, its nymphal development should be considerably affected by the seasonal food supply.
