features
butterfly
The wingspan of the moths is 50 to 60 millimeters, with the females being slightly larger than the males. In contrast to other species of the genus Euthalia, there is no sexual dimorphism between the sexes , since males and females have the same drawing elements. All wings show a yellow-brown to red-brown basic color on the upper side. On the upper side of the forewing , elongated black spots and a narrow black stripe that delimits the submarginal region stand out from the front edge . On the upper side of the hind wing there is a black row of dots in front of the black border. The fringes are checked in black and white. The predominantly dark brown underside of the wing shows a broad, short white band on the front wings and a long, narrow white band on the rear wings. There are also some black and reddish spots. The culled antennae are yellow at the tips. The proboscis is also colored yellow.
egg
The egg is green in color, has a hemispherical shape and has thorns on the surface like a sea urchin . It is deposited individually on leaves of the food plant.
Caterpillar
The caterpillars are colored green. The back line is whitish to yellowish and shows weak gray ring-shaped markings. In the resting position, the caterpillar sits exactly above the central rib of a leaf, with the light back line exactly tracing this central rib, which means that it is hardly visible to potential predators from a distance. The entire surface of the body is provided with thorns from which long stinging hairs extend. When moving, the caterpillar acts like a bobbing twig covered with needle leaves or thorns, which makes it difficult to see.
distribution and habitat
The species occurs in India , Sri Lanka and Bangladesh . Euthalia nais is found primarily in wooded areas, at altitudes from sea level to around 800 meters.
Way of life
The moths occasionally suckle on damp places in the earth or on vegetation that is in biological decomposition in order to take up liquid and minerals. The caterpillars prefer to feed on the leaves of the ebony family (Ebenaceae) or wing fruit family (Dipterocarpaceae).
