Some Details About Ants
Everybody has lived with ants in the house or and the garden all his or her life. Wherever people live, ants live as well, except in Antartica and a few islands, but how much do you really know about them?
Ants evolved from wasps about 120 million years ago and later, as plant life began to diversify, ants diversified and specialized too. We do not know how many varieties of ants there are, but it is reckoned that there are about 22,000. Of those, 12,500 odd have been classified, so there is still a great deal that we do not know about ants.
Despite the huge number of varieties they all have a characteristic shape: a node-like structure with a very slender, wasp-like waist. Ants are insects and they live in colonies from a few dozen to many million individuals. The majority of these individuals are infertile female workers and soldiers.
There are also a couple of males, known as drones, for reproduction purposes and one or more reproductive, egg-laying queens. There will also be a back-up group of reproductive females who can become workers or queens as the nest requires.
Ants are capable of functioning together to resolve pretty complicated social or environmental problems and they have been a source of inspiration to human societies for centuries.
Termites are frequently called ‘white ants’, but in fact they are not at all connected to ants. They are more closely related to cockroaches. The fact that termites and ants share a number of characteristics is ascribed to convergent evolution.
Ants are extremely successful creatures. They make up about twenty percent of the entire land-based biomass and that is greater than the biomass of vertebrates. Most ants will eat anything although some species have specialized. There is a huge disparity in size. Some varieties are only three-quarters of a millimetre long whereas others are fifty-two millimetres in length, which is two inches long!
Ants have jointed antennae unlike most other insects and most of them have rather weak eyesight, some are even blind, but definitely not all. Some ants have excellent eyesight. They do not breathe as we do, but gases passes through their exoskeleton (hard external skin) via valves. They do not have a heart as such either but they do have nerves. Some ants, such as the fire ant, have stings like their ancient relatives the wasps.
Ants come from eggs, but the eggs do not have to be fertilized: fertilized eggs become female and unfertilized develop into male. Ant nurse workers can affect which caste of ant an egg will produce by the kind of food it gives it. Ant eggs need a constant temperature, so nurse workers will often move the eggs from chamber to chamber to keep it perfect.
When an ant hatches out, it is given light duties like looking after the queen and the eggs for a few days and then it is moved on to digging and cleaning the nest. The ants that go out looking for food are the older ants. It is reckoned that they are given this work because it is dangerous and they will more than likely die of natural causes soon anyway.
