Mothra's larval form in the original Mothra was portrayed by a 3 foot-long remote-controlled puppet and a 6 foot-tall, 33 foot-long suit that was operated by eight actors, including Haruo Nakajima and Katsumi Tezuka. The ShodaiMosuLarva is distinct from later Mothra larva designs in that its body is a very light shade of brown, with very pronounced dark spots all over its body. The body is also very elongated and slender. The head is much more rounded than later designs, and features a tall forehead. The ShodaiMosuLarva's eyes are a light blue color and are very small and surrounded by large rounded sockets. The ShodaiMosuLarva's mandibles are relatively small, and the feelers flanking them are thin and located near the bottom of the head.
