The length of the wings is 31–34 mm for males and 28–36 mm for females. Adults are on wing nearly year round. They are notable for the presence of blue pigments in their wings, as opposed to blue created by physical structures. The larvae feed on Alchornea costaricensis and Plukenetia volubilis.
Adult wings are typically held horizontally over the abdomen when at rest. The forewings have two solid color regions: (1) dark gray, sometimes with a blue sheen, in the terminal half of the wing and in the basal half only near the inner margin, and (2) orange in the basal half of the wing except near the inner margin.
The male and female are similar in colour and pattern. [3] The base colour of the upper surface of the wings is greenish white with a violet sheen in the wet-season form, and pearly white in the dry-season form. [3] The forewing has a black-tipped, hooked apex. The wings have a few red eyespots which are ringed with black. There are black spots ...
Besides providing insulation, dark patterns on wings provided by dark colour scales would allow sunlight to be absorbed and thus probably have a role to play in thermoregulation. Bright and distinctive colour patterns in butterflies which are distasteful to predators help communicate their aposematism (toxicity or inedibility) thus preventing a ...
The body of an adult butterfly or moth (the imago) has three distinct divisions, called tagmata, connected at constrictions; these tagmata are the head, thorax, and abdomen. Adult lepidopterans have four wings – a forewing and a hindwing on both the left and the right side of the thorax – and, like all insects, three pairs of legs. [11]
Most have a beige to brown color, and they rarely possess the disruptive cryptic patterns seen in many other geometer moths. A typical ennomiine wing pattern consists of two or three costal to dorsal sections, one of which is often darker in color. There is rarely more than one conspicuous dark or light spot on each side of both wings, and many ...
Adults have a wingspan of 27–30 mm. The wings are brown gray and have crossed brown/gray curved lines. At least one of these lines has a small tooth-like dentation along the length. There is a blotch of black at the postmedian start and a discal spot where the antemedian line crosses the costa. The hindwing discal mark is usually in the ...
Adults exhibit bright wing color patterns which signal their distastefulness to potential predators. Brought to the forefront of scientific attention by Victorian naturalists, these butterflies exhibit a striking diversity and mimicry , both amongst themselves and with species in other groups of butterflies and moths.
