Because I didn't pay attention to sunflowers anymore until there were caterpillars there that became new residents. Do you know which caterpillar I mean, this caterpillar is so small that I can't even get a good focus when I give it a 5x zoom.. And it's just like this that I get a good focus, it can't be more than this, you can notice the white one, it's the caterpillar that inhabits the sunflower now.
