Erik or the Small Book of Insects (2004)

Erik is a Dutch ten year-old schoolboy who is studying insects at school, and gets shown and explained a bit about them by his kind and knowledgeable nature-loving grandfather, whose country estate is a good place to do so and turns out to have a book on insects, which allows Erik to pass for one night, rather like Alice in Wonderland, as a miniature man among thus giant-looking, talking insects, who discuss their and other species and their lives with him, mainly winged ones, such as bee, fly and wasp.

Unfortunately the movie Erik or the Small Book of Insects is not yet available on HBO Max.
