It would certainly tie in with Butterfly House (1985), which is part of the Trail of the Elephants Complex, though insects replacing elephants is a plot twist none of us saw coming.
Hopefully it takes the form of something structured like an Insectarium and Arachnidary rather than a generalised nature trail/kids play area; though anything of an invertebrate nature should be complimenting mammal exhibits in my opinion. In terms of visitor appeal, insects aren’t gonna draw the crowds.
Insects replacing elephants, they may as well shut the zoo down, and sell the land of.
