The document summarizes key information about Ichneumonidae parasitoid wasps: 1. Ichneumonidae is a family of parasitoid wasps that attack immature stages of insects and spiders, killing their hosts and regulating insect populations. 2. With over 25,000 described species, Ichneumonidae is one of the most species-rich branches of the tree of life, though the true number of species is likely much higher. 3. Ichneumonid wasps have a wide global distribution and fulfill an important ecological role as biological controllers, making them promising for biological control applications.

2. The Ichneumonidae also known as
the ichneumon wasps or ichneumonids is
a parasitoids waps family within the
insect order homiptera This insect family
is among the most spesies rich branches of
the tree of life. At the same time it is one
of the groups for which our knowledge
most severely lags behind their
actual diversity. The roughly 25,000
species described today probably
represent less than a quarter of their
true richness but reliable estimates are
lacking, as is much of the most basic
knowledge about
their ecology distribution and evolution

3. Ichneumonid wasps with very few
exceptions attack the immature stages
of holometabolous insects and spiders
eventually killing their hosts
They thus fulfill an important role as
regulators of insect populations both in
natural and semi-natural systems making
them promising agents for biological
control

6. Scientific classification
Kingdom: Animalia
Phylum: Arthropoda
Class: Insect
Order: Hymenoptera
Suborder: Apocrita
Superfamily: Icheunamonidaes
Family: IIchneumonidae latrielly
The distribution of the ichneumonids was traditionally considered
an exception to the common latitudinal gradient in species diversity
since the family was thought to be at its most species-rich in the
temperate zone instead of the tropics but numerous new tropical
species have now been discovered.
