There’s not enough information to give a precise answer, because the insect species is not specified or shown clearly in your message, and different insects have vastly different lifespans (from a few hours to decades).

Why the species matters

  • Many small flying insects (like houseflies, fruit flies, mosquitoes, gnats) live from a few days to about a month.
  • Some famous short‑lived insects, such as certain mayflies, survive only hours to a couple of days as adults.
  • Other insects, especially social insects with queens (ants, termites), can live for many years or even decades in special cases.

Because your question asks “this insect” without a name, image, or description, I would be guessing, which would violate your “avoid_incomplete” and “avoid_harm” rules.

What you can do next

  1. Share a clear photo or the common/scientific name of the insect.
  2. Add basic details:
    • Rough size and color
    • Whether it flies, crawls, or jumps
    • Where you found it (indoors/outdoors, region, climate)

With that information, I can narrow down the likely species and give you a realistic average lifespan range instead of a vague generalization.
