As a child I remember my father using a sticky strip of brown paper to catch and control flies. He would hang it from the ceiling near the garage door. It looked innocent enough but that fly paper always had flies stuck to it. Did Sundews provide the inspiration to design those fly papers?
I have discovered that Sundews are effective at catching aphids. These are small sap sucking pests which can affect North American pitcher plants and Venus flytraps. Growing with other carnivorous plants Sundews act as organic pest controllers that are effective at catching the smaller insects. The Sundews (or unsung heroes) will not only look after your main plants but will get a good feed in the process.
Drosera Burmanni may be small (around 3 cm) in diameter but they are one of the fastest moving Sundews. On the the outside of the leaves are special trip tentacles which fold inwards quickly (within a couple of seconds) when triggered by movement. These tentacles don't have any dew and help to transfer the victim towards the center of the leaf where it's sticky.
