Their traps have evolved from leaves. The leaves are covered in numerous tiny tentacles, with each have a sparkling bead of glue at their tip. Insects are attracted to the plants by the glistening leaves.
When the insect lands the insect is trapped as the glue sticks to them. As the insect struggles other tentacles move towards it, so even if
it was just caught on one tentacle the insect is soon enveloped.
The insect is suffocated by the glue. The whole process can take just minutes.
The plant then excretes an acid with the same strength of battery acid. This breaks down the insect making a digestible soup.
After the plant has finished its meal the leaf opens up again, the trap can be used up to 3 times.
Sundews were one of the first carnivorous plants to studied.
Charles Darwin discovered their insectivorous habitat. In his book "Insectivorous Plants" he was the first to observe how sundews are attracted to nitrogen rich substances
Sundews are found on every continent except Antarctica and are hugely adaptable
