Attacus atlas atlas, cocoons from Thailand.
One of our favourite species. Despite being fairly common in captive broods, obtaining an healthy stock has become quite difficult. Thailand population is the biggest in terms of wingspan (we have seen many specimen above 26cm), they score records in terms of pupal weight and number of eggs laid. Thai atlas have bright colors and more thin terminal tips of the forewings. A single pupae can weight up to 18-19g and, after emergence, it can lay more than 300 eggs.
