Abstract
Behavioral and biological studies pholcid, Holocnemus pluchei (Scopoli, 1763) (Araneae: Pholcidae) at laboratory conditions of 60 ± 70% R.H and 25 ± 2°C. were studied. Female deposited its eggs in webbing basket and carried it all around through eggs incubation period. Newly hatched spiderlings are very transparent and delicate. They stayed in the basket and molted inside or shortly after getting out of it. This spider went through six spiderlings to reach adult as female and five ones as male. First to third spiderlings were reared on Tetranychus urticae mobile stages, while later ones on Ephestia kuehniella moths and Dorsophila melanogaster. Males developed faster than females during 93.5 and 154.9 days, respectively. Life span averaged 342.6 and 130.3 days for females and males, respectively. Females’ fecundity was 68.26 eggs/female. Female produced a mean of 4.0 sacs. Intervals between egg sacs’ deposition averaged 11.2 days. Mean consumption of T. urticae was 266.9 and 217.8 from first to third spiderlings for females and males, respectively. Mean consumption of E. kuehniella and Dorsophila melanogaster was 66.8 and 56.8 individual, for females and males, respectively, during fifth spiderling to adult stage. Mean consumption of E. kuehniella and D. melanogaster was 104.6 for females, during adult stage longevity.
