Common Evening Brown (Melanitis leda) lives in open grasslands across Africa, South Asia and South‑east Asia, parts of Australia. Its conservation status is Least Concern.
Fascinating facts about the Common Evening Brown
- The common evening brown is a butterfly that is most often seen fluttering at dusk, and its flight pattern is anything but smooth. When it does take to the air it darts in an erratic, unpredictable way that makes its movements hard to follow. This erratic flight is a hallmark of the species and is especially noticeable during the twilight hours. Its range stretches across Africa, South Asia and South-east Asia and even reaches parts of Australia.
- When the sun has set, resident individuals of this species become fiercely territorial, driving away any creature that approaches their chosen spot. Even a harmless stone tossed nearby can set off a rapid chase, as the butterflies will aggressively pursue the intruder until it is gone. This defensive behaviour is triggered during the dusk period and shows how sensitive the butterflies are to disturbances in their environment.
- The larvae of the common evening brown have a broad diet, feeding on many grass species such as rice (Oryza sativa), bamboo, Andropogon, Rotboellia cochinchinensis, Brachiaria mutica, Cynodon and Imperata, as well as millets like Oplismenus compositus, Panicum and Eleusine indica. By exploiting this wide range of host plants, the caterpillars can thrive in both cultivated fields and wild grasslands.
- In the dry season the butterfly loses a prominent eye-spot on its hindwing, the ocellus in interspace 2 disappears entirely. Instead of the single large spot, three or four minute white subterminal spots appear along the wing edge, giving the hindwing a more speckled look. This change is part of the overall dry-season form, where the underside colour can vary greatly compared with the wet season.
