Common checkered skipper in the field

The only vegetation flourishing in the dry field are fennel plants, dandelions and a dandelion-like aster relative.

The butterflies are there all day, like this skipper. It is perched on fennel seeds.

Here is the same skipper on a dried dandelion-like aster plant.

Apparently this plant is from the aster family. It looks like a dandelion, but leaves and stems are covered in little spines.
