Microcosmos: Le peuple de l'herbe (1996)

A documentary of insect life in meadows and ponds, using incredible close-ups, slow motion, and time-lapse photography. It includes bees collecting nectar, ladybugs eating mites, snails mating, spiders wrapping their catch, a scarab beetle relentlessly pushing its ball of dung uphill, endless lines of caterpillars, an underwater spider creating an air bubble to live in, and a mosquito hatching.
Microcosmos offers passionate kisses and kinky sex, swashbuckling duels and mass suicide, water bomb attacks and genocide, undercover operations and natural cooling systems. Nonetheless it's suitable for children, complete with an amazing candy factory and a black Sisyphus. In french but limited dialouge anyway, it's all about the cinematography! [imdb] [wikipedia]
