Field spiderling production in A. potteri (Blackwall) was measured utilizing an egg sac overwintering technique. Hatching success was excellent under overwintering conditions of repeated freeze-thaw. The variance in mean egg wt was great but increased egg wt (egg yolk) did not improve hatching success. Dry wt and fecundity were highly variable in this population. Egg wt, egg and spiderling number are positively correlated with dry weight of the female parent.
