Chalcid wasps (superfamily Chalcidoidea) belong to the insect order Hymenoptera, and are one of the largest groups within the order, with some 22,000 known species, and an estimated total diversity of anywhere from 60,000 to more than 500,000 species, meaning the vast majority have yet to be discovered and described. The Leucospidae (sometimes incorrectly spelled Leucospididae) are a small specialized group within the Chalcidoidea, composed exclusively of Ectoparasitoids Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Hymenoptera is one of the larger orders of Insects comprising the sawflies, Wasps Bees and Ants The name refers to

Most of the species are parasitoids of other insects, attacking the egg or larval stage of their host, though many other life cycles are known. A parasitoid is an organism that spends a significant portion of its life history attached to or within a single host Organism which it ultimately kills These hosts are to be found in at least 12 different insect orders including Lepidoptera (butterflies and moths), Diptera (true flies), Coleoptera (beetles), Hemiptera (true bugs), and other Hymenoptera, as well as two orders of Arachnida, and even one family of nematodes. Lepidoptera is an order of Insect that includes Moths and butterflies. True flies are Insects of the Order Diptera ( Greek: di = two and pteron = wing possessing a single pair of Beetles are the group of Insects with the largest number of known Species. Hemiptera is an order of Insects comprising around 80000 Species of Cicadas Aphids Planthoppers Leafhoppers Arachnids are a class ( Arachnida) of joint-legged Invertebrate Animals in the subphylum Chelicerata. The nematodes or roundworms ( Phylum Nematoda from Greek (nema "thread" + -ode "like" are one of the most common

A few species are phytophagous and the larvae feed inside seeds, stems, and galls. Herbivory is a form of Predation in which an Organism, known as a herbivore, consumes principally Autotrophs ref name=Campbell>Campbell Galls or plant galls are abnormal outgrowths of Plant tissues and can be caused by various Parasites from Fungi and bacteria, to Insects Generally beneficial to humans as a group, chalcids keep various crop pests under control, and many species have been imported to control insect pests.

They can be found almost everywhere, particularly on flowers, foliage, and in leaf litter, but are often overlooked due to their very small size, which includes the smallest of all known insects (see Dicopomorpha echmepterygis). Dicopomorpha echmepterygis is a parasitic wasp in the family Mymaridae.

Chalcids are tiny, dark-coloured wasps, often metallic blue or green with complex sculpturing on the body. They are also recognized by the characteristic reduced wing venation, similar to that seen in other superfamilies of parasitic wasps. They have a significant part to play in ecosystems and their true importance must not be underestimated. An ecosystem is a natural unit consisting of all plants animals and micro-organisms( Biotic factors in an area functioning together with all of the non-living physical (

Taxonomy

Chalcidoidea is a superfamily of Hymenoptera, whose family constituency is in constant flux, as new hypotheses of relationships are constantly being proposed and rejected; with the advent of molecular systematics, it seems that the future will see further revisions of the classification in use today. Taxonomic rank ( rank, category, taxonomic category is an abstract term used in the Scientific classification, or Taxonomy, of organisms Hymenoptera is one of the larger orders of Insects comprising the sawflies, Wasps Bees and Ants The name refers to

There are nineteen extant families recognized at present:

There is also one extinct family, Khutelchalcididae Rasnitsyn, Basibuyuk & Quicke, 2004. Fig wasps are Wasps of the family Agaonidae which pollinate Figs or are otherwise associated with figs Francis Walker ( July 31, 1809 - October 5, 1874) was an English Entomologist. Carl Gustaf Thomson ( October 13, 1824 &ndash September 20, 1899) was a Swedish Entomologist. The Chalcididae are a moderate-sized family within the Chalcidoidea, composed mostly of Parasitoids and a few hyperparasitoids The family Pierre André Latreille ( November 20, 1762 - February 6, 1833) was a French entomologist. Encyrtidae is a large family of Parasitic wasps with some 3710 described species in some 455 genera Francis Walker ( July 31, 1809 - October 5, 1874) was an English Entomologist. The Eucharitidae are a specialized group of ant Parasitoids within the Chalcidoidea. Pierre André Latreille ( November 20, 1762 - February 6, 1833) was a French entomologist. Eulophidae is a large family of Hymenopteran Insects with over 4300 described species in some 300 genera ( see List of eulophid genera) John Obadiah Westwood ( 22 December 1805 &ndash 2 January 1893) was an English Entomologist and Archaeologist Eupelmidae is a family of Parasitic wasps in the superfamily Chalcidoidea. Francis Walker ( July 31, 1809 - October 5, 1874) was an English Entomologist. Eurytomidae is a family within the superfamily Chalcidoidea. The group is apparently Polyphyletic, though the different subfamilies may each be Monophyletic Francis Walker ( July 31, 1809 - October 5, 1874) was an English Entomologist. The Leucospidae (sometimes incorrectly spelled Leucospididae) are a small specialized group within the Chalcidoidea, composed exclusively of Ectoparasitoids Johan Christian Fabricius ( January 7, 1745 - March 3, 1808) was a Danish Entomologist and economist Fairy flies are tiny egg parasites and there family Mymaridae is the family of the Alpatus Magnimius(0 Alexander Henry Haliday, also known as Enrico Alessandro Haliday and Alexis Heinrich Haliday (1807–1870 was an Irish Entomologist. Ormyridae is a small family of Parasitic wasps in the superfamily Chalcidoidea. Arnold Förster (1810 - 1884 was a German Entomologist, who worked mainly on Coleoptera and Hymenoptera. The Perilampidae are a small family within the Chalcidoidea, composed mostly of hyperparasitoids The family is closely related to the Eucharitidae Pierre André Latreille ( November 20, 1762 - February 6, 1833) was a French entomologist. Pteromalidae is a very large family of Parasitic wasps with some 3450 described species in some 640 genera (the number used to be greater but many species and genera have Johan Wilhelm Dalman (November 4 1787 Hinseberg, Västmanland - July 11 1828 in Stockholm) was a Swedish Physician and a naturalist Rotoitidae is a very small family of rare Relictual Parasitic wasps in the superfamily Chalcidoidea. Signiphoridae (historically also known as Thysanidae) is a small family of Parasitic wasps in the superfamily Chalcidoidea. Tanaostigmatidae is a small family of Parasitic wasps in the superfamily Chalcidoidea. Tetracampidae is a small family of Parasitic wasps in the superfamily Chalcidoidea. Arnold Förster (1810 - 1884 was a German Entomologist, who worked mainly on Coleoptera and Hymenoptera. Torymidae is a family of Wasps that consists of attractive metallic species with enlarged hind legs and generally with a long ovipositor Francis Walker ( July 31, 1809 - October 5, 1874) was an English Entomologist. The family Trichogrammatidae are tiny wasps in the Chalcidoidea that include some of the smallest of all Insects with most species having adults less than 1 mm in Alexander Henry Haliday, also known as Enrico Alessandro Haliday and Alexis Heinrich Haliday (1807–1870 was an Irish Entomologist. Alexandr (Alex P Rasnitsyn (born 24 September 1936 in Moscow) is one of the world's leading experts in Palaeoentomology.

Of these families, at least five are known to be artificial groups (paraphyletic), and are being - or will be - divided into several families, or perhaps fused with existing families. In Phylogenetics, a group of organisms is said to be paraphyletic if the group contains its most recent common ancestor but does not contain all The most problematic, the Pteromalidae, is, in some classifications, supposed to contain as many as 8 independent lineages, grouped together because of superficial similarities.
