Abstract
The life cycle of Steatoda triangulosa Walckenaer (1802), belonging to family Theridiidae, was studied in laboratory. It had 6 and 5 spiderling instars before adulthood for female and male respectively. Various instars reared on the cotton aphid, Aphis gossypii, vinegar fly, Dorsophila melanogaster, two-spotted spider mite, Tetranychus urticae, stored grain moth, Ephestia kuhniella,and larva of the Cotton leaf worm Spodoptera littoralis. Prey consumption was calculated for different stages. Mating behavior was also described.
