Common Crow Butterfly

Dark brown wings with rows of white marginal spots. Highly toxic due to alkaloids sequestered from its larval food plants.

Males form large aggregations during the dry season, sometimes numbering in the millions.

A bizarre nemopterid with extremely long, thread-like hindwings. Males have hindwings that can be several times their body length.

💡

Its hindwings can be four times longer than the forewings, trailing behind like fine threads.
