Species randa (Rand's Eyed Silk Moth - Hodges#7745)
Hodges Number
se. Arizona, sw. New Mexico, south into central and western Mexico

Distribution is patchy and populations are widely distributed in montainous areas
arid montane forests (usually oak dominant)
in the sw. USA the adult flight period is usually associated with the late summer rains

adults can be collected between late July & early August

Males are readily attracted to lights and fly between 1:30 am - 3:00 am
Captive notes:

early instar larvae seem to prefer and feed almost exclusively on oaks, Quercus spp.

late instar larvae will eat beech, chestnut and occasionally privet.
Life Cycle
eggs laid singly or in clusters on the host plant (twigs, branches, & leaves)

larvae may be abundant between August & October
(5 instars take approx. 6 to 8 weeks to mature and pupate)

Seem to over winter as pupae in silk cocoons
The silk cocoon is similar in size and texture to that of Actias luna (thin and papery). The cocoon is spun in leaf litter on the ground or falls to the ground with the hosts leaves in fall.

adult eclosion occurs the following year

there may be more than one generation annually depending on area
