How long does it take for a Venus Flytrap to digest a fly?

Answer 1

Not very fast at all; one would be tempted to say slowly. The ability of the plant to capture something as fleet as a fly is that it lures the fly into a position of impending capture, between its fangs, so that a little movement effects the capture.

It also depends on the health of the plant.

Answer 2

Depending on the size of the prey, it could take from 5 to 12 days.

Answer 3

Venus Flytrap's traps close at different speeds. If one closes slowly, it means the plant is unhealthy, hence if it closes quickly, it is healthy.

Answer 4

It takes 10 days to digest 1 fly then the leaves open back up.
