Nemoria diamesa is
part of a small group of four southwestern Nemoria species that
are all distinguished by pale, weakly marked, sometimes almost white
hindwings in contrast to the typical green forewing coloring. This
characteristic hindwing coloration and similar genitalic structures are
shared by Nemoria viridicaria,
Nemoria subsequens,
Nemoria diamesa and Nemoria albaria. Nemoria diamesa
is distinguished by the distinctive parallel lines on the forewing, a
significant amount of white striation on the green forewing ground
color, and a somewhat more clearly marked hindwing with some green
coloration and visible pm line markings that are more prominent than
those of N albaria.
Nemoria diamesa has
been collected in Colorado, New Mexico and Arizona. We collected adult
males at an elevation of just over 8,000 feet in the Chiricahua
Mountains in Cochise CO, AZ in late June 2008; Ferguson (1985) reported
collecting diamesa at 8,000 feet in the Great Sand Dunes National
Monument (now Great Sand Dunes National Park) in Colorado between the
dates of June 19-28. A living adult moth from the San Isabel National
Forest photographed in July 2007 is figured here:
