What happens after a black widow lays eggs?
The black widow female often produces several egg sacs. The young spiders emerge from the egg sac after an incubation period of 26 to 30 days, usually during the spring (Table 1). Spiderlings are then dispersed to different geographic areas through “ballooning.” Males reach maturity after 54 to 88 days.
