The spatial distribution patterns, the repulsion among indivduals and the space among individual nests in Agelena limbata Thorell were investigated on the crown of box-tree, Ilex crenata Thumb. The distribution patterns examined by m*-m method of Iwao showed an uniform distribution patterns in the each hill of box-tree. The index of repilation (R) tested using an equation (R=1/(E+1)) of Morisita was from 1.00 to 0.43. The index of repulsion (R) in spider was smaller in the box-tree hill which had high population density than in those which had low population density. This could result from the quantitative difference in food resources for spiders. The space among indivdual nests of spider was nearer in the box-tree hills which had high population density than those which had low population density.
