You don’t really hear of people in the US talking about a movie character as a giant flying moth. In Japan though, everyone knows of Mothra, a character from the Godzilla franchise. While its morphology is slightly off from a real moth (butterfly-like wings, mandibles instead of a proboscis), here we see not just an influence of insects for SF character creation but simply an actual one blown-up in size.

Its unsurprising that Mothra reached so much fame in that country, since entomological enthusiasm is far more widespread in Japan than it is here. One of the traditional things kids do in the summer is to go insect hunting, and in the department stores they sell rhinoceros beetles as pets. That picture is actually of myself as a kid while visiting my grandparents in Japan.
