NaturesGoodGuys offers Praying Mantis Egg Cases, which are perfect for Organic Gardens or Bug-Friendly environments. Praying Mantises serve as versatile allies in gardens, greenhouses, or as pets, voraciously consuming a wide range of insects. These skilled hunters, with their distinctive appearance, ambush prey under natural camouflage. Female mantises lay 50-200 eggs in protective cases during late summer or fall, which hatch after 2-12 weeks of consistent temperatures above 70°F. Young nymphs emerge, seeking prey as they grow into adults with fully formed wings, living several months to a year depending on conditions.
