Pimpla insignatoria
This record describes Pimpla insignatoria (species). Recorded family: Ichneumonidae. Recorded order: Hymenoptera.
Identification and Appearance

The body is entirely shiny black, including a solid black face with no white or yellow markings; legs are predominantly bright orange. Females have a thick, prominent, and completely straight ovipositor projecting from the rear. It lacks the downward-curved tip seen in lookalike genera like Apechthis . Males of the Pimpla genus are incredibly difficult to distinguish from one another without microscopic examination of the genitalia. Easily confused with the highly common Pimpla rufipes . To tell them apart under magnification, look at the color bands on the hind tibia and the precise placement of the tiny breathing pores (spiracles) on the abdomen. Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used and describe the size and identifying characters. Idiobiont endoparasitoid targeting the pupae (chrysalises) of moths and butterflies. https://www.bioimages.org.uk/html/Pimpla_insignatoria.htm No additional images available for this species.

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Pimpla insignatoria. 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.
