We were very lucky to be able to hide and take this picture of a group of wheelbarrows mating. These creatures are usually very shy about interacting, and to see so many in one place is a high spot of the naturalists year. They are a remarkable example of a wild creature using humans to disperse their young.
Before long the females (which can only be recognised by their higher tyre pressure) will lay eggs, which to an untrained eye look remarkably like paper-clips. These will catch on the clothing of passers-by, and some willl find their way into the Taff where they will begin to grow, forming coathangeroid larvae.
As the larval stages grow they develop vestigial wheels, and can often be seen frolicking in the Taff on Friday nights. Naturalists call these trollyofshopping juveniles. These mature into wheelbarrows and crawl with their one mature wheel into hardware shop environmnets.
Next time you see one of these just marvel at the complexity of the natural world.
