In Rebirth of Mothra, the ReoMosuImago's name comes from another kaiju's name, Mothra Leo (モスラレオ?), Mosu, from Mothra's Japanese name, Mosura (モスラ?), and Imago, from the fact that it is a design for Mothra's Imago form.
The ReoMosuImago retains many of the key features of the previous Mothra imago design, but has been changed somewhat. The wings now possess a new pattern and now fold and flap more realistically, giving the prop a more lifelike appearance. The prop's face is wider, while the eyes sit further on the sides of the head. The eyes are changed from blue in color to a turquoise shade. The antennae are much longer and thicker, and feature a tuft of fur at their tips, giving them a closer appearance to real moth antennae. The legs retain the birdlike design, but are longer and thicker, with visible white claws on the feet.
