Pseudomasaris coquilletti
This record describes Pseudomasaris coquilletti (species). Recorded family: Vespidae. Recorded order: Hymenoptera.
Identification and Appearance
In females, the yellow of upper orbits are produced toward ocelli (not so in the similar zonalis ); humeri are more rounded than in zonalis (which have humeri with an obtuse anterior ridge): Antennal segments VI-VII in males are widened gradually to a less well defined club, not much wider than segment VII; front of mid-tibia emarginate (with an apical notch).

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Pseudomasaris coquilletti. 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.
