Fluorescent eggs

These eggs are probably of gastropods or insects. They have a diameter of about 0.3 mm and were located in the forest floor under a thick cushion of moss. I found them in the winter time (!!), in a spruce forest. They fluoresce in ultraviolet light in a green color, an effect which is caused by a fluorophore inside the eggs.
