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

Mimic of Poecilopompilus . There is considerable regional variation in color. Specimens from New England and adjacent parts of New York are darkest, from which area the populations are progressively paler toward the west and south. Darker individuals have the ground color blackish brown, which towards the south and the west becomes fulvous brown or fulvous. Yellow markings are most restricted in the northeastern part of the range, most extensive in the west. Specimens from Arizona and New Mexico have the yellow bands on the abdomen unusually wide, but the yellow on the thorax of only moderate extent. In New England and adjacent parts of New York, the yellow banding on the abdomen is usually restricted to the basal 3-5 tergites. The wings are rather uniformly brown, except that in specimens from the Great Plains and foothills of the Rocky Mts. the apex of the front wing is hyaline. -- Townes & Townes, 1978 Four subspecies have been recognized: Ceratogastra ornata apicalis - all tergites with yellow band; apex of forewing hyaline Ceratogastra ornata ornata - all tergites with yellow band; forewings uniformly deep-yellow pigmented -no image- Ceratogastra ornata polita - only T1-T2 with yellow band Ceratogastra ornata trifasciata - T1-T3 with yellow band; apex of wing strongly darkened

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Ceratogastra ornata. 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.
