What is the main conflict in The Insect Play by Josef Capek?

The Insect Play opens in the woods where a drunken tramp sleeps on the ground. Butterflies flit near him. His slumber is interrupted by a lepidopterist who is collecting butterflies for his scientific collection. The scientist is annoyed that the tramp's movements have scared off the insects. After the scientist leaves to continue collecting, the tramp laments that all the world is paired off into couples.
