Here is something that is very random.
I was flipping Foxtel channels the other night and came across a natural history program called Wild Australia. It covered lots of animals an plants native to Australia, Echidnas, wombats, Tassie devils etc. But it also showed a wildflower I had neve heard of, called a Hammer Orchid. This plant, found in the outback, has two arms. The pollen is stored on one arm, and the other arm has a lump which resembles a female wasp. The plant emits a pheremone which imitates a female wasp to attract males.
When the male locks onto the decoy and wraps its legs around it, the 'arm" of the flower has an elbow which enables it to swing the was over and push it into the pollen, ensuring the wasp carries it of to fertilise other plants.
