The front of her piece depicted pieces of Hagerstown's education and culture, including a stethoscope and graduate's cap for the University System of Maryland at Hagerstown and a child feeding ducks at City Park.
She applied epoxy clay to the wings before painting on them, creating raised images.
"I got the whole layout from the Lord ..." said Butterfield, who lives in Williamsport. "I sort of saw each wing."
Friday was the first day the public saw 60 wings -- on 30 butterflies -- artistically designed to raise money for the new arts school.
In February, the artists, who applied to create statues, met their sponsors at a reception at the Washington County Arts Council on West Washington Street.
Since then, they've worked to get their pieces ready for Friday's display.
The statues will stay downtown until June 20, when a gala auction will be held and some butterflies will be auctioned.
The unveiling created a buzz in and around Public Square, as hundreds of people wandered from statue to statue.
Many pieces drew glowing praise. Everyone seemed to have a favorite -- until they saw the next statue and changed their minds.
At University Plaza, four Northern Middle School students admired four butterfly statues.
All four girls said they will attend the Barbara Ingram School for the Arts when it opens in the fall -- Alexa DumpÃ©, Allison Nichols and Abigail Martinez in vocal and Ashley McElroy in musical theater.
Alexa and Allison said the best statue was "The Butterfly Queen," which featured a woman's eyes. Ashley and Abigail preferred "Jazz and Blues," which had different colors and moods on each wing.
Walking with her mother along North Potomac Street, Jaclyn Madden said she liked a swan-themed butterfly she saw. Jaclyn said she will attend the arts school next semester for photography.
Former Hagerstown resident Barbara Bertrand, now living in Great Falls, Va., admired the entire project and the festive mood it created.
"I think it's wonderful," she said, naming other cities that have done the same thing. "Either this has brought people out -- or the nice weather."
