Butterfly Wing Scale Digital Image Gallery
The clipper is one of the most photogenic butterfly species due not only to its beauty, but to the pose its members often strike. Clipper butterflies have a habit of resting or feeding on flower nectar open-winged for long periods of time. The sound and the flash of cameras pass by these models unnoticed, and not an antennae or wing flutters out of place.
Parthenos sylvia was scientifically described in 1775 by Pieter Cramer, a Dutch merchant of Spanish wool with a great interest in butterflies. The common name, clipper, is an allusion to the speciesí white wing patches that look like the multiple billowing sails on the mighty sailing trade ships of Cramer's day. The white patches are located on the clipper's forewings and stand out against a background that varies in color. The appearance of this Indo-Australian butterfly fluctuates across its broad geographic distribution. The wings may change in size and be blue, green, orange or brown, but the white patches remain unchanged in all of the 26 subspecies.
The clipper butterfly exhibits various modes of protection from predators during its many stages of life. The lives of larval clippers greatly depend upon their meal choices and they prefer to eat the leaves of passion vines and moonseeds. The brown and black striped caterpillars covered with rows of purple spines absorb some of the poisonous organic substances of the plants to make themselves noxious to predators. The chrysalides, however, try to avoid being seen by predators in the first place and appear green or brown, depending on the subspecies. Closely resembling a folded leaf, a clipper chrysalis is extremely difficult to spot in the forests they prefer to inhabit. Clipper adults are so brightly colored that they are easy to see, but protect themselves through unpredictability. Flying in erratic patterns through the tree canopy, clipper adults are difficult to attack or catch unless they stop to feed or rest.
Once captured, the clipper butterfly is relatively easy to breed and rear in a tropical butterfly enclosure. Sufficient quantities of its preferred larval food plant must be available, however, in order to appease the voracious caterpillars. Clipper butterflies are valued by collectors and wild individuals are marketed alongside cultured specimens from tropical butterfly ranches.
Clipper Butterfly Images in Reflected Light
Wing Veins and Pink Scales - Layers of delicate, rounded wing scales in dark and light pink hues can be seen in this stunning image. The prominent wing veins appear as if they were twigs from a tree.
White Wing Scale Patch (Low Magnification) - This image depicts the characteristic white area of scales featured on a clipper butterfly's wing bordered by a black marking. A pair of veins is also present, providing beauty in addition to support and circulation.
White Wing Scale Patch (High Magnification) - In this increased magnification rendition of the previous image, the black marking is no longer visible. Only the numerous rows of pale scales divided by small wing veins remain.
Multi-Colored Wing Scale Pattern (Low Magnification) - The vivid orange, black, and white wing scale pattern of a clipper butterfly can be seen in this photomicrograph. Clippers may alternatively feature blue, green, or brown, depending on subspecies.
Multi-Colored Wing Scale Pattern (High Magnification) - This example of the multi-colored wing scale pattern of a clipper butterfly was captured under a higher level of magnification than the previous photomicrograph. Though the vivid hues may put them at additional risk of predation, members of the species are hard to catch because of their erratic flight patterns.
