I found these opalescent eggs on a blade of grass. At first I thought they were just a patch of white from a bird dropping, but decided to look more closely and this is what I saw. Scores of minute eggs all clustered together on both sides of the grass blade, the length measuring perhaps 2 cm. I had to place a leaf under the grass blade in order to photograph the eggs. I think they are quite beautiful! Diane tells me that these are moth eggs.
