DISTRIBUTION:
Catocala caesia (8837.1), Caesia
Underwing or Bluish-gray Underwing, (wingspan: 47-55mm) flies in the mountains of southeastern
Arizona: Cochise and Pima counties,
and in southwestern New Mexico, and southward through the Sierra Madre
Occidental in Chihuahua, Mexico.

holotype male, 28 May 1985, courtesy of David Hawks, from ZooKeys online publication.
The forewing is a blotchy blue-grey-brown with some lighter areas. The double am line with its lighter "filler" is dark and thick/diffuse. The distinct pm line is black,
thinner than the am line, and traced outwardly with a thin white line. There are no greatly elongated teeth.
The reniform spot has a pale brown center and is faintly outlined in black. The small subrectangular subreniform spot is almost pure white, is indented on its inward side
and is narrowly outlined in black.
The hindwing is bright yellow, with unchecked/lightly checked yellow fringes. There is some light brown scaling in the basal median area. The inner black band is
relatively thin, turns at an acute angle toward the im, but is bluntly truncated well bfore reaching the inner margin. It seems to be followed by a small dark dot.
The outer margin is bluntly truncated well before reaching the inner margin. It is followed by a larger black dot near the base of the inner margin.

SCENTING AND MATING:
Catocala caesia females
emit an airbourne pheromone and males use their antennae to track the
scent plume.
EGGS, CATERPILLARS, COCOONS AND PUPAE:
Eggs are deposited on
tree bark in the fall and hatch the following spring.
Larval Food Plants
Listed below are anticipated ?? primary food plant(s) and alternate food plants.
It is hoped that this alphabetical listing followed by the common
name of the foodplant will prove useful. The list is not exhaustive,
although some species seem very host specific.
Experimenting with closely related foodplants is worthwhile.
