This species is deemed to be the first scientifically described insect species from the Hawaiian Islands, as the first specimen was collected on the day of Cook's landing on the island of Kauai at the 21. January 1778.


The Rasp Potter Wasp didn't build own burrows but occupied pre-existing cavities, which it filled with caterpillars of Microlepidopterans as food for its larvae.
