  • Some Observations on the Reproduction of Agelenid Spiders

抄録

In this paper are reported the results of the Author's observations on the reproduction of Japansee Agelenid Spiders collected every month in Miyazaki Prefecture.<br> 1. All of the three species of this genus were observed on their life cycle through a year. (Tabl 1.)<br> 2. Sex ratio of Agelenid spiders has become clear by counting both adult sexes during the mating period. (Table 2.)<br> 3. The sex ratio is different not only with species but also with the individuals of the same species.<br> 4. After copulation, the appetite of the female spiders sharply increases, and they eat the male spiders (fig. 1.) and the other spiders as well.(Table 3)<br> 5. The shape of the egg-cocoon varies with species. However all of the cocoons are made of double silk sheets. The eggs are neatly piled inside the inner silk. A female spider usually produces only an egg-cocoon during her life span with some exceptions in which two or three are porduced.
