In German, this series was called "Biene Maya", in English "Maya the Bee". It features two young bees having adventures out and about, discovering new things and helping other insects. Among their friends are a wise grasshopper, they also encounter ants, beetles, earthworms, and some not so nice wasps and the spider Thekla.
I would say the target audience is 2 - 8 year old children. The animation is good for its age, but you do notice that the series is over 25 years old, however, it holds up very well compared to modern children's TV series, especially as the characters and story lines are well thought through.
Most 20 minute long episodes will convey values such as friendship, helping others, etc., but the messages are never too blatant.
