 Ichneumonoidea
The species of Ichneumonoidea vary tremendously in size, from approximately 1 mm in length to 5-6 cm (even larger if the ovipositor of some larger species is included).
Ichneumonoidea have been present since at least the early Cretaceous, being represented by Tanychora from Transbaikalia (Townes, 1973), as well as several genera of Eoichneumonidae from Australia, Siberia and Mongolia (Jell and Duncan, 1986; Rasnitsyn and Sharkey, 1988).

Eventually, almost all of them were discarded as more detailed studies appeared in the literature, leaving the correct placement of the family among the Hymenoptera as a problem that is still in need of a solution.
Many past and contemporary authors insisted in the idea that the Stephanidae would be part of the Ichneumonoidea (e.g.
Sharkey & Wahl (1992), however, have demonstrated that the Stephanidae share only one of the autapomorphies of the Ichneumonoidea (loss of 2r-m on the front wing), which also occurs, by convergence, in all major groups of Apoidea, showing that there is no evidence to suport Stephanidae as part of Ichneumonoidea.

 Diversity and abundance of <i>Ichneumonoidea </i>(Hymenoptera) in eucalypt arboreta of differing structure   (Site not responding. Last check: 2007-11-01)
Abstract: We studied how the diversity and abundance of endemic wasp parasitoids of the superfamily Ichneumonoidea changed as trees aged and the responses of populations of these insects to tree species composition and amount of understorey using three experimental field trials on the outskirts of Canberra.
In 6552 hours of Malaise trapping we caught 1408 Ichneumonoidea; these were almost equally divided between Ichneumonidae (696 individuals representative of 15 subfamilies and 74 mostly morphospecies) and Braconidae (712 individuals).
We found a trend towards greater abundance of Ichneumonoidea in arboreta comprising approximately 38:62 eucalypts and acacia compared with arboreta comprising 10:90 eucalypts and acacia or those comprising only eucalypts.

 Insects Ichneumon Flies - Super-family Ichneumonoidea   (Site not responding. Last check: 2007-11-01)
Until quite recently this great group comprising what are popularly known as the Ichneumon flies* (Both the scientific and the popular names of this group were derived from the name of the so-called Egyptian Ichneumon or Pharaoh's rat, which devours the eggs and young of the crocodile and was held sacred by the ancient Egyptians.
The species of the Ichneumonoidea are without exception parasitic upon other insects, and for the most part upon insects which are injurious to vegetation.
They are on the whole distinctly beneficial insects, and as will be shown in the detailed life history which follows, they may be responsible for the absolute saving of great damage to the shade trees of our cities as well as to agricultural crops by their widespread destruction of injurious insects.

 PEET - Monographic Research in Parasitic Hymenoptera
Improved taxonomy and more natural classifications of parasitic wasps will enable better characterization and management of biological diversity, and it will directly support research directed at a more sustainable agriculture with fewer negative impacts on the environment.
The project will address the taxonomic needs in four families representing the four major lineages (superfamilies) of parasitic Hymenoptera: 1) Braconidae (superfamily Ichneumonoidea), 2) Encyrtidae (superfamily Chalcidoidea), 3) eucoiline Figitidae (superfamily Cynipoidea), and 4) Diapriidae (superfamily Proctotrupoidea).
The collaborative nature of the project and the outstanding specialists in each major group that have agreed to participate will provide exceptionally broad training and experience for the students in all aspects of modern, collection-based systematics research.

3) There are interesting differences among Ichneumonoidea, Chalcidoidea, and Diptera in species distribution over host feeding niches.
When parasitoids are divided following the usual dichotomy in koinobionts and idiobionts, differences are found between host feeding niches in the relative importance of the two groups.
4) Parasitoid communities in general, and especially the Ichneumonoidea, decrease in diversity with decreasing latitude, resulting in a lower overall diversity in the tropics.

A selected group of taxa, designated “skeletal taxa”, will be used to reconstruct the evolutionary relationship among the superfamilies.
More intense sampling of 400 species or more will be conducted with each of the hyper-diverse clades, such as the Aculeata, Ichneumonoidea and Chalcidoidea.
Working as a team in the creation of the skeletal matrix will help standardize morphological terminology across the Hymenoptera.
