Graellsia isabellae or Spanish moon moth

This species is also called the stained glass moth. The upper side of its wings is green, with very dark outlines. Its antennae are unusual, in the shape of a brush. In the Department of Hautes-Alpes, the species is primarily found in the mountain pine forests. It tends to be active at dusk. During the breeding season (April-June), the female releases sex pheromones when the temperature rises above 13°C. Her eggs are spherical in shape and are 2 to 3 mm in diameter.
