Voubi mask, comb and butterflies Attacus lemairei

Very large glass entomological box (39 x 50 x 6 cm) in perfect condition, containing a Voubi (Gabon) "passport" mask and a comb from the same ethnic group, framed by four immense Attacus lemairei butterflies (Saturnidae family), rarer but almost as large in terms of surface area as the better-known Attacus atlas, considered the world's largest butterfly. These giants of the Heterocera family (moths) are strictly endemic to the island of Palawan, in the southwest of the Philippines. The two males on the left, which can be recognized by their large, feathery antennae, and the females (on the right in the box) with their much smaller antennae, do not feed as adults, living solely on the reserves accumulated by their caterpillars, only to reproduce and then die quickly. Two Cytheronia regalis, also from the Saturnidae family, are joined by the box, but they don't feed as adults either.
The box and butterflies are in perfect condition.
