And the Green Grass Grew All Around (1931)

It's a shotgun wedding, a big boy fly to a little girl fly, with her bearded dad holding the shotgun. A wedding party ensues, with an energetic hoe-down involving lots of dancing and playing insects. The preacher-bug gorges himself on cake. The ball bounces over a live field of tall grass. A boy and girl bug smooch in the middle of a sunflower.
