Why do butterflies rest in a head-downwards position ?

There are several reasons for this. Many Nymphalids including Hamadryas, Prepona, Panacea and the Red Admiral Vanessa atalanta habitually bask high up on tree trunks, with wings outspread, and head downwards. They often appear to be observing the activity below them, and males certainly use these high vantage points to watch out for females flying below them in the forest. An additional advantage of adopting this position is that sunlight hits the wings more squarely, allowing the butterflies to warm themselves more quickly. |
