There are many different species of known beetles in Ontario. They often live on plants, but many burrow in the ground and some even swim. Most species of beetles have a life cycle of one year, and go through four different stages. The eggs, laid by the adult female, hatch into larva, which feed and grow. The larva turns into pupa which does not feed and eventually turns into the adult. Beetles adapt to their environment and time the laying of their eggs to reach adulthood when food is most plentiful. Ontario has long harsh winters with little vegetation and beetles will be identified in spring or summer when plants and ponds are alive with food.
