Red velvet mite, which is as big as one of the letters in this sentence, has a peculiar mating habit.

The male releases its sperms on small twigs or stalks in what scientists call the "love garden", then lays down an intricate silken trail to the spot. When a female stumbles upon this trail, she will follow it to seek out the "artist". If she likes his work, then she will sit on the sperm.

However, if another male spots the garden, he will trash it and lay his own instead! (Source)
