No, flame fruit, also known as Physalis angulata, cannot fly. It is a plant, and plants do not have the ability to fly.
Flame fruit is a type of ground cherry, a small, edible fruit that grows on a vine. The fruit is encased in a papery husk, which gives it its distinctive appearance.
While flame fruit may be mistaken for a flying insect due to its bright orange color and the way it hangs from its vine, it is simply a plant that grows on the ground.
