More bugs likely die from predation in the wild than from old age, as many insects and other invertebrates have relatively short lifespans and are a vital food source for a wide variety of predators. Additionally, many insects have high reproductive rates, which can offset the loss of individuals to predation.

There are also many insects that have a long lifespan, and for those, age-related death is more likely. e.g. the Queen ant, termite, or honeybee, and Cicadas, Praying Mantis' etc.
