When I go for a walking with the dog in the river nearby every morning, I watch butterflies.
I watched at least three kinds of butterflies this morning.
One of them was size of a thin purple corbicula.
Another one of them was bright golden yellow with size of a swallowtail butterfly.
Other one was swallowtail.
The creatures around the river are various.

I am worried about there being the corpse of a lot of earthworms in the gutter of the concrete by shore protection works.
A wall of the concrete is more taller, and when the earthworm falls once, they cannot crawl up from there.
