Each worm has male and female segments, which reproduce via hemaphroditism.  The male segment fertilises the female segment. The reproductive organs then deteriorate, leaving only a uterus full of eggs.  This then detachesfrom the rest of the worm and migrates to the large intestine, where it ruptures releasing the eggs.

The eggs released are infective to oribatid mites, which act as the intermediate host.  These mites live in the ground, feeding on plant debris. These are ubiquitous, but most numerous on permanent pasture in the summer months.
