CU Museum: Exhibits: Moth Matters: With Images by Joseph Scheer

Because most moths are nocturnal and most humans are diurnal, we simply do not encounter each other all that frequently. We must make the effort to look for them. Here are some ways to encounter moths.

Porch lights: Many moths are attracted to the light of incandescent bulbs. Simply turn on your porch light at dusk and remember to step outside periodically and look to see what is there. (They don't normally ring the doorbell.) Look around the light on the walls, ceiling, if it is covered, and on nearby screens or bushes.

Black lights or mercury vapor lighting: Much like the porch light idea taken to the extreme, this is a serious technique used by insect collectors but easily can be modified for home use. A head lamp and lawn chair add to the enjoyment. Try to remember to dress in black.

Sugaring: Sugaring is a delightful way to attract and feed your backyard moths, although this only works for species that feed. You won't get the giant silk moths this way but you can attract many beautiful species. Sugaring involves mixing up a concoction of moth bait (food), painting it on your trees and fence posts, and waiting. See our References on Moths page for recipes and pointers. ***CAUTION***: Bears may also be attracted to moth bait!

Flowers for day-flying species: Not all moths are nocturnal, some are crepuscular (twilight) or diurnal. Many of these species feed at flowers. Hawkmoths, looking much like bumblebees or hummingbirds, are often encountered at tubular flowers. Other moths have lifecycles tied very closely to certain flowers, on which the adult moth rests and feeds and where the caterpillars develop. Look closely at flowers; some moth may be living there.

Event Announcement:
To get a perspective on how many species occur in the Boulder area, come to Dr. Paul Opler's lecture entitled "The Exciting World of Colorado Moths" on April 7th at 7pm.
