Dielis tolteca, the Toltec scoliid wasp, is a species of hymenopteran in the family Scoliidae. It is commonly found on plants in the genus Solidago. Female D. tolteca have extensive orange on at least three tergites of the gaster. The first segment is variable from a complete band to no band at all, and every possible degree in between. The only other orange-marked ally, D. dorsata, has the orange restricted to the second and third tergites of the gaster.
Male D. tolteca have four pale yellow bands on both the tergites and sternites of the gaster and a yellow band on the pronotum. As with the females, the most similar species is D. dorsata, which has sparser setae on the external valve of the penis and lacks banding on the sternites. The males further share the paler markings with D. plumipes, a species that is sympatric in Texas and which has the clypeus and pronotum entirely black. Another ally, D. pilipes, has a fifth band on the abdomen (only shared with D. tejensis) and is structurally distinct from all other members of the genus by the microstructuring on the frons, propodeum, mesonotum, and hind tibiae.

Possible
About 20% of wildlife watchers report a Toltec Scoliid Wasp sighting in Ría Lagartos Biosphere Reserve on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 112 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January
In that month about 40% of wildlife watchers report a Toltec Scoliid Wasp in Ría Lagartos Biosphere Reserve on a given day, against under 5% in April–May, August and October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Toltec Scoliid Wasp sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Toltec Scoliid Wasp sightings, Ría Lagartos Biosphere Reserve has the highest daily chance: about 20%. Next come Channel Islands National Park (United States, about 10%).
Same order: Hymenoptera
The closest relatives of the Toltec Scoliid Wasp that you can see in Ría Lagartos Biosphere Reserve (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Mexican Pitted-Stingless Bee (about 20%), Ectatomma tuberculatum (about 20%) and Mexican Honey Wasp (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Toltec Scoliid Wasp is recorded against all the insects logged in Ría Lagartos Biosphere Reserve (15 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
