Overlaying squelchy sounds onto time-lapse footage, award-winning microphotographer Wim van Egmond creates an entertaining and informative short about three different earthworm species found in Western Europe: Aporrectodea caliginosa, Lumbricus rubellus, and Lumbricus terrestris.
The film documents their different feeding and burrowing behaviors over the course of 11 weeks in 2019, and catches sight of a small worm cocoon (egg casing). He writes:
The footage of an adult worm [A. caliginosa] carefully “tucking in” its freshly laid egg cocoon to ensure it is in good contact with the soil (and thereby preventing it from drying out) is the most exciting part of the whole movie. And, of course, after two months the cocoon hatches and there are baby earthworms!
Filmed on behalf of Soil in Action, as well as for use in classrooms and for educational lectures, the time-lapse captures A. caliginosa‘s preference for eating soil organic matter (vs leaves). L. rubellus feeds on leaf litter and the fungi growing on it. L. terrestris appears to drag its food down into permanent burrows. Notes throughout the film translate each scene.
