Semar bag is a very unique plant because it can prey on various insects that are nearby. This plant is very rare so it must be on guard sustainability, so as not to extinct. Semar bag itself can only prey on insects when he was an adult. First he will open his pockets and emit an odor that can invite insects, then after an insect comes in he will close his pocket so that the insect is trapped and start digesting it...
