Hymenoptera, the order that includes ants, bees, sawflies, and wasps is one of the most diverse groups of animals.
Hymenoptera are valuable to both man and the environment.
Perhaps most beneficial of all are the myriad natural enemies of insects found among the non-social wasps and, especially, the parasitoid wasps.

The order Hymenoptera is pronounced "hy-men-OP-ter-a." This name comes from the words, "hymen," which is a Greek word for membrane, and "ptera," which means wings.
Many Hymenoptera feed on plants, visit their flowers, or are parasitic on other insects that eat plants.
Hymenoptera have chewing mouthparts, often with large mandibles in soldier ants.

 Sex determination in Hymenoptera
The most obvious of these is the evolution of social behavior, in which most members of a community sacrifice their own reproductive potential, to provide food and protection for the few reproductive members and their offspring.
In addition to unique selective pressures governing sex determination in some Hymenoptera, analyses of the evolution of sex determination in the order are hindered by the fact that in many cases, the actual Hymenopteran being studied is not the only organism with a vested interest in determining its sex.
While in recent years evidence has mounted that a great number of biological pathways are conserved across the animal kingdom, one developmental process which for the most part has evaded this grand display of commonality is that of sex determination, which in contrast seems to have evolved rather rapidly (Marín and Baker, 1998).

 Introduction to the Hymenoptera   (Site not responding. Last check: 2007-11-07)
The Hymenoptera include famous examples of social insects, such as honeybees and true ants; these insects have developed regimented social systems in which members are divided into worker, drone, and queen castes.
Such social hymenoptera may live together in nests or hives of many thousands of individuals, all descended form a single queen.
Not all hymenoptera are social, however; many live a solitary life, coming together only for a brief mating.

Herbivory is common among the primitive Hymenoptera (suborder Symphyta), in the gall wasps (Cynipidae), and in some of the ants and bees.
Despite their small size and characteristically narrow host range, these wasps are highly abundant and exert a tremendous impact on the population dynamics of many other insect species.
Although some species are regarded as pests (e.g., sawflies, gall wasps, and some ants), most members of the Hymenoptera are extremely beneficial -- either as natural enemies of insect pests (parasitic wasps) or as pollinators of flowering plants (bees and wasps).

In all Hymenoptera except the sawflies, the abdomen is joined to the thorax by a very narrow connection.
