How Long Do Beetles Live?
Beetles have a relatively short lifespan. Its life cycle begins during the mating season between spring and fall, when male and female beetles mate or reproduce asexually. A mother will usually choose the same habitat in which she grew up to produce her offspring. She will lay her eggs directly on a food source, whether it is wood, plant leaves, dung, or wherever prey is plentiful. Eggs can hatch in a few days or up to several months. Larvae go through the larval stage, where they feed, grow and shed their exoskeleton.
The developing beetle then goes through the pupal stage. Some beetles take only a few weeks to transform, while other species take years. During this time, the pupae do not eat, but remain dormant with reduced activity. Once beetles have grown into adults, their lifespan can vary from 10 days to 6 months, depending on the species.
