Ichneumon deliratorius
This record describes Ichneumon deliratorius (species). Recorded family: Ichneumonidae. Recorded order: Hymenoptera.
Identification and Appearance
Length 14 to 20 mm. This is a mainly black species. The female has a broad pale band across the otherwise dark antennae; there is also a pale spot on the scutellum and at the tip of the abdomen. The larvae of Coelichneumon deliratorius are parasitic on various moth larvae. Poorly recorded in Britain but probably fairly frequent.

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Ichneumon deliratorius. Species-specific details appear above.
Group overview
Hymenoptera includes over 150,000 described species of ants, bees, wasps, and sawflies. Earth harbors approximately 20 quadrillion (20×10^15) ants, with a combined biomass of ~12 megatons of dry carbon - exceeding the combined biomass of all wild birds and mammals (PNAS, 2022).
Ecological role of the group
About 35% of the world's food crops depend on animal pollinators. The chocolate industry, valued at over $100 billion, depends on pollinating flies and midges. Ants are the dominant soil engineers in most terrestrial ecosystems, turning more soil than earthworms in many habitats.
Economic and practical significance of the group
Pollinators contribute $235-577 billion worth of annual global food production (FAO). In the U.S., bee pollination alone benefits crops valued at $18 billion annually, and honey bees are responsible for $5.4 billion in agricultural productivity. Between April 2023-2024, 55.1% of managed honey bee colonies were lost. The U.S. bee population dropped from 5 million to 2.5 million.
