The Deadly Venus FlyTrap [Dionaea muscipula]

 The Venus FlyTrap is a carnivorous plant that feasts on insects and spiders alike. It belongs to the phylum Anthophyta and can be found in wet, swampy environments. They usually grow in poor soil with few nutrients, so their ability to eat insects is necessary for their nutrition, energy, and survival. Healthy venus flytraps will produce seeds after pollination, but a faster way to artificially force venus flytraps to asexually reproduce is by division, or dividing the plant into pieces that can be grown separately and that may later mature. The sweet smell of its nectar is what lures insects and spiders within its petals. The venus flytrap will take over one week to digest properly.
