Chiracanthium japonicum is well known as a poisonous spider. The geographical distribution of the spider was studied in various localities in Japan during the period from 1959 to 1975. This spider was recognized to distribute widely in Japan. From the study on the vertical distribution at Mt. Kyoga located on the Nagasaki-Saga prefectural border, Kyushu, South Japan, they were found widely over various heights, though they were most abundant in the zone from 200 to 300m in height. Ecological field study was made on the seasonal change and habitats at the mountain of Shironokoshi in Nagasaki Prefecture during the period from March to September in 1967. The total number of 1331 spiders, which consisted of 577 male and 754 female spiders, was recorded from the survey areas. They were distributed mostly in bush, especially in Gramineae groups during the period from May to July. The laboratory observation was made on their behavior, especially on mating, breeding and hatching. Among them, it was the most dramatic behavior that the spiderlings caught and killed their mother after the second molting. The parasitic insect which was observed on the back of this spider was identified as Homonotusiwatai Yasumatsu (Hymenoptera; Pompilidae). The best method for eliminating this species to prevent arachnidism is by means of the weeding of the grass belonging to the family Gramineae at areas close to houses in April before the final molting of male spiders. Children must be taught that this spider is dangerous, because they are more often bitten than adults.
