Natural History

Behavior

The Unicorn Clubtail are often found perched along the shoreline facing the water. They frequently perch on the ground, in sand or mud, but will also perch on lily pads, algae mats, logs, or on vegetation along the shore. They are sometimes found in the same habitat as Lilypad Clubtails

Habitat

Muddy-bottomed lakes, ponds and slow moving streams with little vegetation

Reproduction

Males patrol over the water or from low perch. Females lay eggs alone by tapping their abdomen on the water's surface
