What worm's egg is in the photo?

Sorry, according to my limited knowledge, I can't confirm which kind of worm's egg is in the photo. To determine the species of eggs, you need to consult a professional entomologist or go to a professional entomological museum or biological laboratory for identification. However, I can tell you some general information about eggs.

Eggs are part of the reproductive organs of insects and other invertebrates, and are usually laid by mothers under suitable environmental conditions. Eggs usually have different shapes, sizes, colors and textures, which can help us identify different kinds of insects.

Some common insect eggs include:

-The eggs of butterflies and moths, usually attached to plants, are yellow or white;

-Usually the eggs of bees and ants in the nest are yellow or white;

-eggs of cockroaches and salamanders, usually brown or black on the ground;

-The eggs of mosquitoes and flies, usually in water, are gray or green.

However, these are just some examples. In fact, the types of eggs are very diverse and require professional knowledge to identify them. If you have any questions or concerns about eggs, you'd better consult a professional entomologist or biologist.
