Education, Gardening and Fun: Spreading the Joy of Butterflies to Everyone!
“Blue Moon, You Saw Me Standing Alone”
“Blue moon, You saw me standing alone Without a dream in my heart Without a love of my own.” –Frank Sinatra, First Verse
Graceful Blue Moon (Hypolimnas bolina) butterflies dance in our garden with elegant dress here in Tonga in the South Pacific. Males all appear the same. However, the females are not only dimorphic (featuring different colors and patterns from the opposite sex), but also rarely look the same as other females, demonstrated by this photo essay.
The female Blue Moon butterfly hovers over a plant to check for ants which might eat her eggs. After selecting a plant which has no ants on it, she lays at least one but often two to five eggs on the undersides of the leaves.
For months, we could not figure out which of the many host plants, that Blue Moon butterflies are known to use, might be available in Tonga. Then one day, to my complete surprise, a female Blue Moon “saw me standing alone” and landed right at my feet. She deposited eggs on a nearby plant, which we later discovered was Nodeweed. Mystery solved!
Blue Moon butterflies are found from Madagascar, off the southeast coast of Africa, through South and Southeast Asia, to South Pacific islands (including French Polynesia, Tonga, Tuvalu, Samoa, and Vanuatu), and in parts of Australia, Japan, and New Zealand.
If you live in or happen to visit their range, keep an eye out for the snazzily-dressed males in their velvety black tuxedos with iridescent purple cummerbunds and the females styling their myriad elegant tapa-cloth formals. Two ladies never want to wear the same dress to the ball.
“Blue moon, Now I’m no longer alone Without a dream in my heart Without a love of my own.” –Frank Sinatra, Chorus
