I was wondering what shaped homes and buildings would an insect like creature that can walk upside down and fly make?
This question about a birds house brings up some good points like needing a large open space to fly inside Planet of the Aves: New Nests
For this species the larvae stage can chew up and spit back out material to form structures, the species has evolved into being quite intelligent so building shapes that would require structural support is possible, theoretically they can make quite extravagant buildings if they wish and some do.
The larval stage prepares for its later butterfly like stage of life by building a home for which it will live and truly be able to enjoy later, almost like preparing for retirement but instead it will be the stage where they can enjoy life more as they can fly and see the world and find a mate.
I almost want some of their buildings to be very beautiful in their design but in a way that is very different from humans, like looping tunnels within the house that they can fly through to enter different rooms but I am not sure if this is a practical idea, also in the butterfly like stage they can walk upside down, so rooms can be suspended from the ceiling but due to gravity they still couldn't do as much upside down as on a floor such as eating or any hobbies.
So my question is what would be the most practical shaped homes and buildings for an intelligent insect species that can fly and walk upside down? and I also don't mind some visually pleasing ideas that may be less practical but would just look cool and still make some sense.
