This record describes Hemiptarsenus ornatus (species). Recorded family: Eulophidae. Recorded order: Hymenoptera.
Identification and Appearance
Female antennal club entirely whitish, thus showing black scape, pedicel and four further segments before the white club. Scutellum longer than broad. Females with 2-3 darkened bands. Thorax of female marked with yellow-orange at the sides and usually also towards the front of the scutellum, the axillae and the side lobes of the mesoscutum. Reared from cocoons of Stigmella (Lepidoptera) and mines of Phytomyza (Agromyzidae) and Lithocolletis (Gracillariidae). Askew, R.R.

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Hemiptarsenus ornatus. 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.
