E-Mail a Friend Plot Summary When an ant scout returns home with a mysterious crystal, the queen ant decides it is the most delicious food she has ever tasted.
Polynesia 42 Ants are found on all continents except Antarcticaand only a few large islands, such as GreenlandIcelandparts of Polynesia and the Hawaiian Islands lack native ant species.
Most ant species are omnivorous generalistsbut a few are specialist feeders. Their ecological dominance is demonstrated by their biomass: More than 12, species are currently known with upper estimates of the potential existence of about 22, see the article List of ant generawith the greatest diversity in the tropics.
Taxonomic studies continue to resolve the classification and systematics of ants. Online databases of ant species, including AntBase and the Hymenoptera Name Server, help to keep track of the known and newly described species. The head, mesosomaand metasoma are the three distinct body segments.
The petiole forms a narrow waist between their mesosoma thorax plus the first abdominal segment, which is fused to it and gaster abdomen less the abdominal segments in the petiole. The petiole may be formed by one or two nodes the second alone, or the second and third abdominal segments.
Insects do not have lungs; oxygen and other gases, such as carbon dioxidepass through their exoskeleton via tiny valves called spiracles.
Insects also lack closed blood vessels; instead, they have a long, thin, perforated tube along the top of the body called the "dorsal aorta" that functions like a heart, and pumps haemolymph toward the head, thus driving the circulation of the internal fluids.
The nervous system consists of a ventral nerve cord that runs the length of the body, with several ganglia and branches along the way reaching into the extremities of the appendages.
Like most insects, ants have compound eyes made from numerous tiny lenses attached together.
Ant eyes are good for acute movement detection, but do not offer a high resolution image. They also have three small ocelli simple eyes on the top of the head that detect light levels and polarization. The head has two strong jaws, the mandiblesused to carry food, manipulate objects, construct nests, and for defence.
The legs terminate in a hooked claw which allows them to hook on and climb surfaces.
Queens shed their wings after the nuptial flightleaving visible stubs, a distinguishing feature of queens. In a few species, wingless queens ergatoids and males occur.
Workers of many species have their egg-laying structures modified into stings that are used for subduing prey and defending their nests. Often, the larger ants have disproportionately larger heads, and correspondingly stronger mandibles. These are known as macrergates while smaller workers are known as micrergates.
In a few species, the median workers are absent, creating a sharp divide between the minors and majors. The smallest and largest workers in Pheidologeton diversus show nearly a fold difference in their dry-weights. The role of workers may change with their age and in some species, such as honeypot antsyoung workers are fed until their gasters are distended, and act as living food storage vessels.
These food storage workers are called repletes. Usually the largest workers in the colony develop into repletes; and, if repletes are removed from the colony, other workers become repletes, demonstrating the flexibility of this particular polymorphism. If the egg is fertilised, the progeny will be female diploid ; if not, it will be male haploid.
Ants develop by complete metamorphosis with the larva stages passing through a pupal stage before emerging as an adult. The larva is largely immobile and is fed and cared for by workers. Food is given to the larvae by trophallaxisa process in which an ant regurgitates liquid food held in its crop.Two Bad timberdesignmag.com can be helpful if students have been working on narrative writing of some sort and have been exposed to the idea of writing about setting,but it is not necessary.

There are three kinds of ants in a colony: The queen, the female workers, and males. The queen and the males have wings, while the workers don’t have wings. Red Ants Pants Foundation Announces Grant Recipients.
