Ants
Order Hymenoptera
Introduction
Ants belong to the order Hymenoptera which also
includes bees, wasps and sawflies. There is believed to be
over 11,800 known ant species in the world, including
Bull Ants, Meat Ants, Fire Ants and Honey Pot Ants. Ants
have been colonising on earth for over 150 million years
. They are extremely social creatures and enjoy living
in colonies. These colonies are made up of several castes
(different forms of mature insects living in colonies)
including a reproductive queen, workers and soldiers with
several subcastes which include winged males & females.
The winged males and females only appear during mass mating
flights in which the male dies after mating and the female
sheds her wings to start a new colony or to join one already
existing.
A colony is begun when a female ant lays a small number of
eggs. She feeds the larvae to maturity and these essentially
become the first workers, building nests and looking after the
queen. Once the queen has her worker ants under control she can
sit back and relax. Well not altogether relax, her role is
purely laying eggs.
Habitat
Ants generally build their nests on the ground,
though some species are known to build their nests in
trees or in leaves. Some nests can be very complex
with many
chambers and interconnecting tunnels, while
others are very simple. Every ant colony in the
animal kingdom has their own special way of designing
their home. Some even build climate control nests with
ventilation holes which they can open and
close.
Predators
The ant has numerous predators. One of the
most unique is the ant-mimicking spider. This spider has
evolved to look very much like its favourite food, the
ant. The spider uses its two front legs as antennaes and it has
a pinched in area along its cephalothorax to give it the
illusion of having three body parts (smart). As it
inter-mingles with the ant colony, it just picks off an ant
whenever it feels hungry or inclined. Lucky for us humans we
haven't evolved into our favourite food!
