Nice shot of the insectivorous plant Drosera binata, which is very common around Wenty Falls.

Cheers, Greg

Thanks again, Greg. Does the Drosera actually attract insects? by odour, colour, or merely physical contact? What insects are mostly caught? ants? or winged insects?

Most interested.

The insects are attracted by the drops of sticky moisture on the leaves, which is their downfall. Odour (of decaying bugs) and colour (like red meat) may also play a part in catching food. The fluid is sticky, and the digestive enzymes in it start digesting the insects once they are 'held'. The leaves are also slightly 'active', and will cup themselves around the trapped insects (very slow moveemnt, often over several minutes to hours). I have seen a wide range of 'bugs' in the leaves, but mainly small flying insects. Ants are usually too clever to get caught, and one goup (the Assassin bugs) have managed to find a food source in sucking the juices from other trapped insects.

Glad to provide any info I can, Greg.
