Toltec Scoliid Wasp
Dielis tolteca
This record describes Dielis tolteca (species). Recorded family: Scoliidae. Recorded order: Hymenoptera.
Identification and Appearance

Females are separated from D. pilipes by their orange-marked abdomens as the only such campsomerine species of the western US. Structurally, the propodeum is smooth, in contrast to the punctate propodeum of D. pilipes . The orange abdominal color is only shared with D. dorsata , which has been introduced to Florida from the Caribbean. Males are separated from D. pilipes by having four abdominal bands (5 in D. pilipes ). They are immensely similar to the eastern D. plumipes , which is only known to co-occur in Texas.

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Dielis tolteca. 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.
