The Oregon swallowtail butterfly was adopted as the Oregon's official insect with the approval of Senate Concurrent Resolution No. 6 by the Oregon Legislature.

A true native of the Northwest, the Oregon Swallowtail is at home in the lower sagebrush canyons of the Columbia River and its tributaries, including the Snake River drainage. This strikingly beautiful butterfly, predominantly yellow, is a wary, strong flier not easily captured.


Senate Concurrent Resolution No. 6

WHEREAS, insects represent by far the largest group of living organisms; and

WHEREAS, the recognition of a state insect would further educate by promoting a greater interest and understanding of entomology; and

WHEREAS, insects have survived well in the face of exploding population and remain a major area of nature study left available to young and old alike; and

WHEREAS, the Oregon swallowtail butterfly (papilio Oregonius) is indigenous to the Oregon territory, contains the word "Oregon" in its common and scientific names, is of great aesthetic value and has no objectionable qualities; now, therefore,


That the Legislative Assembly adopt the Oregon swallowtail butterfly (papilio Oregonius) as Oregon's official insect to join the beaver, the chinook salmon, the Oregon grape, the Douglas fir, the western meadowlark and the thunderegg as unique symbols of Oregon's distincitve history and environment.

Filed in the Office of the Secretary of State July 17, 1979.

Where Butterflies Grow

Joanne Ryder

Where Butterflies Grow, by Joanne Ryder, 32 pages. Puffin (June 1, 1996) Reading level: Ages 4-8. In a field of lacy leaves, a small caterpillar hatches, grows, and sheds its skin, becoming a smooth, green creeper. It eats and changes some more, then in a sequence of remarkable close-ups, spins a sliken sling in which to pupate--until it finally bursts forth as a brilliant black swallowtail butterfly. Includes suggestions on how children can grow butterfiles in their own gardens.

I Wish I Were a Butterfly, by James Howe. 40 pages. Voyager Books (February 28, 1994) Reading level: Ages 4-8. After the frog at the pond's edge tells him that he's ugly, the cricket of Swampswallow Pond loses his zest for life and for singing. The glowworm and the ladybug try to persuade the cricket that he's just as good as the rest of them, while the dragonfly declares, "Wishing is a waste of time." Finally, the Old One, a spider who lives on the other side of the pond, spins a wise tale about the real beauty of friendship and convinces the cricket to sing again. A simple fable that deserves to stay in print a long, long, time.
