Q.I Have Something Like Slug Eggs In My Border, But They Are Bright Green About 5mm Diameter! Any Idea What They Are?
There are quite a few of them spread all over a patch about 1 meter square. I have done quite a lot of gardening and I have never seen these before even though we have lived in this house for 14 years. We often have toads here, could they be toad eggs?

Toad eggs are usually found in rows. Insect eggs are soft and squishy. Fruits or seeds will have a hard coating. You can press on one (with gloves) and see what comes out. If it's an insect egg, the insect may come out.
I did some research and couldn't find what would have green eggs, but soil laying insects include slugs, snails, beetles, weevils, grasshoppers, and ants. Ground pearls are related to scale, but are chiefly found in grass.
