Emperor Moth(Saturnia pavonia)
Emperor moth of the Saturniidae family was described first in 1758 by Swedish botanist Carl Linnaeus in his book 10th edition of Systema Naturae. It occupies the British Isles and is the only member of its family to inhabit that region.
Description and Identification
They appear black and orange at the onset, transforming to green upon maturation, with red and yellow spots and black rings.
The larva pupates in a pear-shaped, light brown cocoon.
Sexual Dimorphism: Present
Color and Appearance: Males – When opened,the forewings are brown and white with orange and red bands, whereas the hind wings appear orange. The chief attraction that makes it look beautiful is the black and orange eyespots on all four wings. When closed, the overall coloration does not change, though only one or two of the four eyespots may be visible.
Females – When opened, the fore and hind wings are grey, with white bands to the sides. The eyespots remain similar to that of the males. When closed, the wing pattern remains the same.
On the whole, the females are larger than the males with a neater appearance.
Wingspan: Females: 8 cm; Males: 6 cm
Flight pattern: Fast and consistent
Season: Mid-April – late June
The eggs are small and brown, and the females lay about 75 of them on average at a time.
