Morgan sums up a discussion on Lubbock's experiments in which the ants failed to utilize particles of earth for bridge-making, with the suggestive remark that " What these valuable experiments seem to show is that the ant, probably the most intelligent of all insects, has no claim to be regarded as a rational being.". A more general and practical interest attaches to the insects which act as their intermediate hosts. Insecta also has further orders but it is the main class for insects.
