Males claim territories and perch on waterside plants, waiting for females. In the diorama as well, a male can be seen awaiting a potential mate.
Males are metallic green with pale blue veins on their wings. Females are blackish-brown in both their wings and body, with white spots on their wings.
Upon spotting females, males exhibit courtship behaviors, such as hovering or floating on the water's surface with their abdomens arched upward. Females lay their eggs on submerged plants alone.
Habitat of This Animal:
A:Forest along the valley - A2:Forest along the mountain streams
In Tokunoshima Island, abundant rainwater carved the ground, forming many rows of ridges and valleys. Plants adapting to the flowing and drying up of water grow in the harsh environment, where water swells and depletes every time rain falls. The waterfront is also a habitat for many creatures, including endemic species, with frogs and dragonflies breeding.
