About Attacus atlas in brief

Summary Attacus atlasThe Atlas moth is one of the largest lepidopterans, with a wingspan measuring up to 24 cm and a wing surface area of about 160 cm2. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Both forewings have a prominent extension at the tip, with markings that resemble the head of a snake. Females release powerful pheromones through a gland on the end of the abdomen to attract a mate. A female will wait for a male to come along and be fertilised, lay eggs and die.

Adult Atlas moths are weak, unsteady fliers. To conserve energy, the moths rest during the day and fly at night. The caterpillars hatch after approximately two weeks and feed voraciously on the foliage of citrus, cinnamon, guava, and evergreen trees. They spin a 7–8 cm long papery cocoon interwoven with desiccated leaves and attach it to a twig using a strand of silk. Adults emerge from the cocoon after approximately four weeks depending on environmental factors.
