Description and Life Cycle
Adults are 8–10 mm in length with 16–20 mm wingspans. The outer half of their forewings are bronze, copper, or dark gray in color, while the upper half are yellowish-gray, with a dark band at the intersection between the two. The moth larvae are off-white with brown heads. When these larvae mature, they are usually about 12 mm long.
The entire life cycle of this species may take 30 to 300 days. Female moths lay between 60 and 400 eggs on a food surface, which are ordinarily smaller than 0.5 mm and not sticky. The eggs hatch in 2 to 14 days. The larval stage lasts from 2 to 41 weeks, depending on the temperature.

Famous quotes containing the words description and, description, life and/or cycle:
“He hath achieved a maid
That paragons description and wild fame;
One that excels the quirks of blazoning pens.”
—William Shakespeare (1564–1616)
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“Like plowing, housework makes the ground ready for the germination of family life. The kids will not invite a teacher home if beer cans litter the living room. The family isn’t likely to have breakfast together if somebody didn’t remember to buy eggs, milk, or muffins. Housework maintains an orderly setting in which family life can flourish.”
—Letty Cottin Pogrebin (20th century)
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
