Aguna asander is found in Central and South America, including Costa Rica, Panama, and northern Colombia. It inhabits rainforests and cloud forests, preferring shaded areas with dense vegetation and nectar-rich flowers.
The Asander Hairstreak exhibits a slow, fluttering flight, often resting with wings closed to blend into foliage. Males are territorial, perching on leaves, while females lay eggs on host plants. Adults feed on nectar, and larvae feed on legumes.
Aguna asander is not currently endangered, but habitat loss from deforestation is a growing concern. Conservation efforts aim to protect rainforest habitats and promote native plant restoration.
