The book had some equasions, which were of no interest to me, so I skipped them. There was a lot of fascinating facts, I still can't get over.
Eggs which haven't been fertilized result in life of male bees (I always thought there was necessity of sperm entering the egg for life to begin). The ant workers change their duties during span of their life. They start in nursing, but then can move to foraging or fixing nest, or defense. Social insects do not play.
Science that deals with animal communication is called zoosemiotics. The lack of personal recognition, or rich emotional potential in ants is supported by an anecdotal experiment. Scientists covered an ant with pheromone of death. The other ant picked it up and carried it to disposal grounds three times, before the first one was able to clean the scent from its body (no hard feelings).
Insects communicate by stroking, grasping, tasting, attenations, etc. Bee can learn as many as five turns in a maze, remembering distance, color of a marker and angle of a turn. Social insects are able to master associative and latent learning, but not insight or transfer learning.
There are many differences even inside one species. The book is very interesting, technical in some places.
