The darker and more greenish specimens from Amador County, California, described as Catocala mcdunnoughi browerarum Johnson, do not differ from nominate material and variation is not consistent geographically (e.g., many Plumas and Butte county specimens are more evenly greenish brown). Thus, the subspecies has been (2010) synonymized with the nominate species. David Hawks.
"Catocala mcdunnoughi is most similar to C. chelidonia (occidentalis), but the more brownish and mottled ground color of C. mcdunnoughi will usually separate these species. No other small Catocala species in the region has postmedial lines with two large teeth only at M1 and M2." David Hawks.
The Catocala mcdunnoughi caterpillar shows a preference for Quercus chrysolepis.

SCENTING AND MATING:
Catocala mcdunnoughi females emit an airbourne pheromone and males use their antennae to track the scent plume.
Right: Catocala chelidonia occidentalis or C. mcdunnoughi male, Frazier Mountain Rd, 5750', Ventura County, CA., September 7, 1991. Kelly Richers, collector, at uv light.
Catocala chelidonia occidentalis or C. mcdunnoughi female, two miles south
of Fishcamp, 4700'.
Madera County, CA.. Kelly Richers, collector, at uv trap.
The late flight season (September) and high elevation (5750 feet) for the male also suggest C. mcdunnoughi.
In their recent (2010) publication, Gall and Hawks do not list either C. c. occidentalis or C. mcdunnoughi from Ventura County. They do site C. c occidentalis from Madera County, but C. mcdunnoughi is not listed there.
