The book in question was written prior to 1990. The pages probably had no words — I was able to read at the time, so either it was not narrated or the words were not memorable. Each page, or pair of pages, featured a scene in some fictional town which resembled a human town but populated by arthropods: insects, spiders. The arthropods were not anthropomorphic, but assuming the roles of humans in that town. E.g.
- At a dinner table, a father daddy-long-legs (harvestman) was seated at the head of a table as a pillbug was being served on a platter. The mother was a preying mantis IIRC.
- A large centipede was crawling down a street, colored like a school bus.
I can't remember if the other insects were riding on it, or if the bus simply resembled a centipede on the outside.
The pages had about the same ratio as the Magic School Bus books IIRC.
