Adoption of the California State Insect

In 1929, the Lorquin Entomological Society of Los Angeles conducted a statewide survey of active entomologists to select a butterfly that would best represent the State of California.

Winning the day, over such notables as Lorquin's admiral and the California sister butterflies, was the California dog-face butterfly. (At the time, the dog-face butterfly was also referred to as the California dog head butterfly and the flying pansy.)

The California Blue Book, published by the State Legislature in 1929, indicated that entomologists had selected the small, orange and yellow butterfly as the California insect.

The Bureau of Entomology in the California Department of Agriculture used a representation of the California dog-face butterfly on its documents, labeling it the "California State Insect."

But no official action had occurred... until over 40 years later, when Mrs. Betty Harding and Mrs. Shirley Klein and their fourth-grade students at Daily Elementary School in Fresno took action and enlisted the help of State Assemblyman Kenneth L. Maddy.

Mr. Maddy introduced Assembly Bill No. 1843 (AB 1834) proposing that the California dog-face butterfly (Zerene Eurydice) be named the official State Insect. His bill was read for the first time on March 15, 1972 and referred to the Assembly Committee on Government Organization.

"Dog-Faced Butterfly Has Wings Clipped"

As the California dog-face butterfly had served for over forty years as California's state insect in an unofficial capacity, one would not have expected any objections to making it official. Surely the small butterfly had earned the honor?

On May 25, 1972, with a committee vote of 6-2, Mr. Maddy failed to garner the needed eight votes to recommend the legislation to a floor vote. It wasn't clear why two members voted against the bill, but a bill to designate an official state fossil also gone down to defeat earlier in the day.

The Fresno Bee wrote, "Dog-Faced Butterfly Has Wings Clipped."

Assemblyman Maddy vowed to fight on and promised a better result when the full committee was present in the next week.

Good to his word, Mr. Maddy moved the bill out of committee and to approval by the full Assembly on June 19. 1972.

A month later, on July 20, the Senate voted 29-0 to approve AB 1834.

On July 28, 1972, Governor Ronald Reagan signed Assembly Bill No. 1834 designating the California dog-face butterfly the official State Insect of California.
