Mike Van Buskirk, San Antonio, Texas writes, "Many believed this species to be rare, but larvae can (often) be found commonly in late August and
early September, particularly around classic collecting areas like Pena Blanca Lake in Santa Cruz County in SE Arizona. My personal belief is this species isn't
particular attracted to lights, and may only fly in the early evening.
"In all the years I have collected P. terlooii, I have never seen P. terlooii flying during the day. In my experience they
are night-fliers, and do come to lights. I collected my first adult at light in 1971, at a gas station in Nogales, Arizona."
The upperside of the forewing is uniform olive green with a darker median band. The upperside of the hindwing is red with an olive green border.
Mike Van Buskirk writes, "The larval hostplants are documented as Boerhaavia species (at least two--B. coccinea and coulteri have produced larvae). Boerhaavia is in the plant family Nyctaginaceae. Larvae, to the best of my knowledge, and I have collected in SE Arizona for more than 30 years, has never been found on any Onagraceous plant.

"The larvae are well pictured in the website, Moths of SE Arizona, maintained by Bruce Walsh at the University of Arizona.
"The larvae tend to be nocturnal, or at least hidden during the brightest time of the day. I have found them readily with a flashlight at night, and during cloudy and rainy weather. I have found larvae hiding under debris near the hostplant during the day, but hardly ever up feeding until later afternoon or evening.

Bruce Walsh also reports the larvae as being not uncommon, but indicates he has had success finding them during the day.
Mature larvae pupate and overwinter in shallow underground burrows.
