The genus name "Perigonia" POSSIBLY was chosen to reflect the bud like tufts of hairs near the tip of the abdomen.

"Stulta" means stupid or foolish, an unusual choice for a species name!

The pronunciation of scientific names is troublesome for many. The "suggestion" at the top of the page is merely a suggestion. It is based on commonly accepted English pronunciation of Greek names and/or some fairly well accepted "rules" for latinized scientific names.

The suggested pronunciations, on this page and on other pages, are primarily put forward to assist those who hear with internal ears as they read.

There are many collectors from different countries whose intonations and accents would be different.

FLIGHT TIMES:

Perigonia stulta has been taken in Costa Rica in all months except March.
