10 Animals That Only Live for Some Days

Mayfly - Mayflies live just 24 hours—some only for a few minutes! They exist solely to mate and die.

Gastrotrich - These tiny water animals live just 3 to 4 days. They feed, reproduce, and disappear quickly.

Drone Ant - Male drone ants live a few days, only to mate with the queen. They die right after reproduction.

Housefly - A housefly's life is short—10 to 14 days. Still, it can spread plenty in that time!

Fruit Fly - Fruit flies live for 8 to 10 days. Used widely in genetic research due to their short lifecycle.

Gall Midge - This insect’s adult life spans just 1 to 2 days. They don’t even eat—only breed and perish.

Luna Moth - Luna moths live for 5–7 days without a mouth! They survive just long enough to reproduce.

Fire Ant Male - Male fire ants live just days, dying post-mating. Their short lives support colony survival.
