The life cycle of a leather jacket grub, also known as a crane fly larvae, consists of four stages: egg, larva (grub), pupa, and adult. Eggs are laid in moist soil or grassy areas, where they hatch into grubs. These grubs live underground, feeding on roots for several months up to 2 years, depending on environmental conditions. After this period, they pupate, transforming into pupae, and finally emerge as adult crane flies to repeat the cycle. Observation of your local environment can show these stages, especially in late summer to fall when adults are most visible.
