Animal Behaviourist Derek Wragge Morley examines ants in mazes.
C/Us of ants crawling about - could be seen through a microscope? Seems to be just their silhouettes, as if they are seen through tissue paper lit from behind.
We then see Animal Behaviourist Derek Wragge Morley doing research work into ants. He puts a clump of earth and ants into a maze and covers it with a piece of glass. Then he observes how the ants find their way out.
More C/Us of ants; one of them is a queen ant. C/U of an ant running about a maze and trying to find his way out. We are told that intelligent ants have a nervous breakdown when faced with an unforeseen obstacle so "that must explain what happens when you sit on one", says commentator.
