This reads like two books in one. The first part is exactly what you would expect from the title. The second book… Let us talk about it later
First, let us discuss the first part of the book.
Very nice. It talks about the myths (Point the Elder thought there were dog-sized ants guarding mines in India and Ethiopia) and facts (Ants are more numerous than humans which you probably knew; they come in innumerous species which you may have guessed; their total weight is equal to the total weight of all humans – based on estimates of course – which may have surprised you a lot)
The author talks of the incredible variety in ants and even their lifestyle – some species have the queen sucking fluid from the body of her own offsprings. He talks about worker ladies who are female but have no interest in sex and spend their entire lives in hard labour. He talks about male ants and the Queen, whose entire purpose is to simply lay eggs continuously for the good of the colony.
Talks about collaboration where a group of ants, collaborating, can kill an insect ten or twenty times the size of a single ant. He talks about the lives of ants which is in days if not weeks and how the queen, in contrast, can live for several years.
Ants date back far into antiquity, where they evolved from wasps.
You also learn about strange behaviours : For instance the parasitic Queens of Teleutomyrmex schneideri have no workers and live all their lives attached to the abdoman or thorax of queens of Tetramorium caespitum
Some queens mate only with one male, some with several but a male, if he gets a chance at a queen, can mate only ones as the sperm is collected during the larval stage and the testes ‘are completely degenerate’ by the time they reach adulthood. The mating is bizzare and takes place in air, just after a rain. When the males and females fly up one and one time only and mate. The details differ. Some would be queens mate with several males and some with just one.
In all cases, the life of males ends after that. In many cases they all fall to the ground and lose their wings and die or killed and eaten by others (including other worker ants). The queen also loses the wings but she keeps thousands or even millions of sperm particles inside a pouch to repeatedly fertilize her eggs throughout her life. In some gruesome cases, the female kills the male by cutting its thorax during the act of mating.
We learn that the queen can decide whether to have male offspring or female depending on the needs of the nest! And the colony selects which of them will be queens and which the workers (who are sterile and selected for the hard work in the community). The care that the ants give to the eggs laid by the queen (until they hatch) is awesome and interesting to read.
The building of nests, and the catching of prey through a trap by one species of tree dwelling ants, are nice to read as well.
How some ants create tunnels small enough to raid the colony of a larger sized ant, so that the latter cannot follow when these escape with the former’s pupae (to eat) and food; how some ants have developed a face armor that is flat that is used like a stone wall to deny entry to attackers at the mouth of their nest – these are a few nuggets you pick up.
What you already knew probably is that ants use chemical smells to communicate and as markers for the way.
You learn about parasitic queens, those who takeover by killing another queen, and also about the constant need to kidnap larvae to supply workers for the current hive as the natural born children of the usurper queen do not have the ability to care or forage – only to fight and kill. They employ also techniques to confuse the intended target colony. Smearing their pheromones on themselves to disguise their alien nature, secreting ‘calming pheromones’ that sap away the will to fight in the target colony or ‘propaganda pheromones to make the worker ants of the target fight to death among themselves! Oh my, what variety and viciousness in the small insect kingdom!
The weaver ants and the army ants also lead amazingly diverse lives with their own idiosyncracies.
He turns to the symbiotic relationships and genetic mimicry. Aphids being cultivated by ants (which we knew about) and also used as food in times of need (which we did not know probably), other predators mimicking the ants or aphids by sight or smell only to feast on larvae of ants once safely inside, one variety of caterpillars providing honeydew like secretion in return for protection from ants – all are told in an easily accessible and astonishing style. The authors also talk about symbiosis with plants.
Makes you think, right? The ‘common’ ants are not so common after all, if you consider the entire species.
Things get even more complex with the workers contriving to selectively kill off broods of rival fathers within the same nest.
After all this excitement, the second part of the book is a huge disappointment. First the authors pleads for more funds for ant research (And you realize that you have no power to help, unless in an improbable coincidence, you happen to control the purse strings of bio research!). Then they go into AI and how ‘everything’ seems to be borrowed from ant behaviour. A slightly excessive claim, in my opinion. It is as if after writing the first half of the book, the authors gave it to propaganda division of their unit to fill in the other half.
I do understand and agree that the scientific work is based on ants and the authors did act as consultants to the projects but this subject more appropriately belongs in a AI book or a technology book. The title does not lead one to expect that material in this. \
In this sense, this is the opposite of The Sound of a Wild Snail Eating by Elizabeth Tova Bailey, which we have reviewed earlier. There you do not expect astonishing details of the life of the creature (snail) and so you are pleasantly surprised.
I would say 6/ 10
