Biological aspects of the spider species, Artema atlanta Walck. was studied at constant conditions in laboratory (25±2°C and 60-70% R.H.) when fed on four preys individuals. Larvae of the vinegar fly, Dorsophila melanogaster and the fruit fly, Ceratitis capitata.were introduced to the first and second spiderlings, stored grain worm moth, Ephestia kuehniella and the vinegar fly, Dorsophila melanogaster introduced to the third and fourth spiderlings and house flies, Musca domestica, stored grain worm moth, Ephestia kuehniella and the vinegar fly, Dorsophila melanogaster introduced to the fifth and sixth spiderlings. Incubation period averaged 11.5 ± 1.20 days. The pre- oviposition period was 19.81 days before laying eggs, while the oviposition period averaged 32.8 ± 3.77days; the post- oviposition period averaged 134.9 ± 3.72 days. The obtained result revealed also that; the highest average rate of consumption when the spider Artema atlanta Walck. Feed on Musca domestica , Ephestia kuehniella and the vinegar fly, Dorsophila melanogaster the 5th and 6th spiderlings and represented by 73.0 and 84.1 individual for female and 62.0 and 72.0 indi. For male 5th and 6th spiderlings, respectively.
