Certain biological aspects of C.jovium were studied at constant conditions of 25°C and 60-70% R.H. using C.capitata adults as preys. Fertilized spider females deposited one egg sac with 300-350 eggs. The incubation period was 14.06 ± 1.83 days. Females went through 8-9 spiderlings before reaching maturity, while males went through 7-8 spi­derlings. The average developmental duration was 230.62 ± 16.07 days and 169.73 ± 14.53 days for female and male individuals, respectively. the corresponding respective averages of total life span were 387.62 ± 0.83 and 234.73 ± 0.83 days. Average pre-oviposition and post oviposi­tion period were 70 ± 1.14 and 77.14 ± 7.6 days, respectively.
