Diet and Behavior
Diet: Polylectic bee (generalist pollen/ nectar collector) frequenting especially Larrea tridentata (creosote bush), and Kallstroemia grandiflora (Arizona caltrop), both in Zygophyllaceae (Caltrop family). Other plants visited: Solanum elaeagnifolium , Solanum rostratum ( Solanaceae / Nightshade family), Calliandra schottii , Senna bauhinioides (formerly in genus Cassia ; both Calliandra and Senna in Legume family/ Fabaceae ) [see Cazier & Linsley, 1974, and Hurd & Linsley, 1975, references below].

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Protoxaea gloriosa. 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.
