Life Cycle
overwinter as adults. Eggs that are laid singly on leaves or stems hatch in approximately one week. Big-eyed bugs have five nymphal instars, each of which lasts from 4 to 6 days. Adults live approximately one month and a female can lay up to 300 eggs during her adult life span.
Big-eyed bugs are among the most abundant and important predaceous insects in many crops in the US(3), e.g. on cotton plantations
