How long can a firefly live in a jar with no holes?

A firefly can typically survive in a jar without holes for only a few hours to a day, depending on various factors like temperature and humidity. Without air circulation, the oxygen levels will quickly deplete, leading to suffocation. Additionally, lack of access to food and water will further shorten its lifespan. To ensure the well-being of fireflies, it's important to release them back into their natural habitat as soon as possible.
