Like most moths, Speranza colata, flies at night and remains inactive during daylight hours. Rather than hide this one tends to sit where a similar piece of tree bark or lichen might be. The point is not to look like something edible to insectivorous birds.

Many kinds of moths can be attracted to ultraviolet or mercury-vapor lights set up in sycamore canyons from July through September. A typical set up with a bevy of entomologists in rapt attention is shown below.

Geometridae -- Inchworm Moth Family
