The picture compares the digestive process by enzymes among two plants of Venus Flytrap species, one is small and the latter is large.
Overall, two plants have the same three main hunting stages, starting with triggering hairs and only digestive enzymes released after a prey is confimed.
Regarding the smaller one, when the prey enters the trap, sensory hairs are triggered there to close the mouth, creating an airtight chamber which ensures the prey cannot escape. After that, the digestive enzymes are released, breaking down the prey gradually. When the nutritions of insects are absorbed, the trap will open and ready for the next hunting.
However, the larger Venus Flytrap counterparts operates quite differently. The intial stage is similar, where the prey is detected, activating the sensory hairs and making the trap close. Nevertheless, the larger thorn gaps of the plant make the trap cannot close fully. As a result, when the small insects escape, the trap open again.
