Uranami-shizimi | Long-tailed Blue

The butterfly that is widely distributed around the world prefers warm areas and migrates frequently.
In Japan, as temperatures rise, they migrate north from warmer regions, but they die in regions with cold winter temperatures.
It is characterized by its shiny blue wings and tails attached to the back of its wings. The tail looks like antennae, and the black spots on the wings that look like compound eyes make it difficult to tell which direction their face is facing.
