What is the life cycle of a brown widow?

The life cycle of a brown widow spider (Latrodectus geometricus) includes four main stages: egg, larva, pupa, and adult. Adult female brown widows lay eggs in silk sacs, which typically contain 100 to 400 eggs. After about 2-3 weeks, the eggs hatch into spiderlings, which are small and vulnerable. They mature into adults in about a month, with females growing larger than males and often producing multiple egg sacs throughout their lifespan.
