Hi everyone. Can anyone tell me what are the insects on the picture? It's the first time I see them on my plants and they don't seem very nice

Thanks!

flea beetles.

Diatomaceous earth is my go to pest control for many crawling things including lots of different beetles. It is not a poison, it is the shells of diatoms, tiny marine creatures. On a microscopic level, they are very sharp like bits of glass. To us macroscopic humans, it just feels like soft powder, though you wouldn't want to breathe too much of it in to your lungs. You don't know it, but you have eaten it, because grains stored in silos are treated with it to keep weevils out.

Ok thanks. Do they spread to nearby plants (other species) or do they tend to stay on the same plant species?

They spread and will eat many different kinds of plants.

As pests go, they are far from the worst. Plants can tolerate a whole lot of those little pinholes without being seriously bothered.

They do like solanacea -- yours are tomatillos?

Look at my poor neglected eggplants

They are ground cherries. It's a little seedling I put with my flowers because I didn't feel like tossing it after planting the good ones in the garden. I may get like 5 fruits from it haha

It doesn't seem your eggplants have the same pests on them - do they?

Oh well, ok then. I don't think I'll bother doing something. They don't seem to be interested in what's around for now.
