In females, the pale patches toward the tip of the forewing are pure white. In males, some or all of these patches are light orange. Adult butterflies feed on koa sap, so are often seen on tree trunks near wounds where sap is flowing. Males appear to be more attracted to these "sap fluxes" than females. A male butterfly sipping from a sap flux on koa. These sap fluxes are often fermented and bubbling, giving off a "beery" aroma that may be attractive to the butterflies. Immature stages For the purposes of documenting Kamehameha butterfly populations, the immature stages are extremely helpful.
The first reason is that they are potentially easier to find and photograph than adult butterflies, since they cannot move quickly or very far. The second reason is that when we find the immature stages at a site, we know that the butterflies are actually using that site to breed and reproduce, whereas adult butterflies can actively disperse far from their breeding sites, or get blown off course.
Therefore, immature stages give us more precise information about Kamehameha butterfly habitat. Eggs Eggs are tiny, about the size of a pin head, and are laid only on caterpillar host plants on the upper or lower surface of leaves. For a list of host plants and how to recognize them, please visit the host plants page.

Caterpillars Larval stage Caterpillars start out tiny and go through several developmental stages called "instars" , shedding their skin between each stage. Color varies a lot among individuals. The beauty of this Hawaiian Butterfly is related to many breeds of butterflies found all over the world.
But today, this blog is about the remarkable story behind the Kamehameha Butterfly. The ancestors of these 2 butterflies made it here from North America or Asia millions of years ago.
They then slowly changed enough over an extended period to become their own species. They cut a flap of leaf, covering themselves, which they secure with silk. Older caterpillars sit still on the branches, waiting for nightfall.
When the sun has set, and the forest birds have gone to sleep, they venture safely onto the leaves to eat. Their chrysalis is also well-camouflaged, looking like a withered leaf. It takes a little over 2 weeks for the chrysalis to become a butterfly. This Butterfly was formally named in to honor the Royal House of Kamehameha. This royal family unified the Hawaiian Islands in They reigned until the death of Kamehameha V in Again, it has been suggested that the bulbuls are responsible.
It is believed that they have switched their diet from the butterflies to the caterpillars, which consequently show no variation depending on the morph Stimson and Kasuya-Maiko, Text by Rob Nelson. Stimson and Kasuya-Maiko. Report comments if you believe they do not follow our guidelines.
