| Gorytes sp. 1 | Infused wings, extensive yellow on face, mostly dark hind tibia and tarsi. |

| Psammaletes | | |
| Psammaletes mexicanus | |

| CRABRONINAE | | |
| Crabronini | | |
| Anacrabro | | |
| Anacrabro ocellatus | |
| Ectemnius | | Most observations of this of this difficult genus are stuck at genus level. |
| Ectemnius continuus | |
| Ectemnius cf. lapidarius | Three plausible but unconfirmed observations. |
| Lestica | | |
| Lestica sp. | Three genus-level observations. |
| Lindenius | | |
| Lindenius sp. | One genus-level observation. |
| Larrini | | |
| Tachytes | | Frequently observed but difficult to ID to species from photos. |
| Tachytes cf. distinctus | Several unconfirmed observations appear referable to this taxon. |
| Tachytes pennsylvanicus | Research-grade ID from photos of a specimen. |
| Oxybelini | | |
| Oxybelus | | Many genus-level observations, more than one species may be present. |
| Oxybelus sp. | |
| Trypoxylini | | |
| Trypoxylon | | |
| Trypoxylon cf. collinum | Dark tarsi, orange band on abdomen. |
| Trypoxylon lactitarse | |

| PHILANTHINAE | | |
| Aphilanthopini | | |
| Aphilanthops | | |
| Aphilanthops frigidus | |
| Cercerini | | |
| Cerceris | | Difficult genus with only one confirmed species; there are unconfirmed but, we think, plausible observations of C. atramontesis, bicornuta, clypeata, halone, and nigrescens, plus many genus-level observations that could reflect any of these or even addtional species. |
| Cerceris fumipennis | Common and distinctive. |
| Philanthini | | |
| Philanthus | | |
| Philanthus gibbosus | Perhaps our most common Crabronid species. |
| Philanthus lepidus | |
