Vumbaco said the yearlong project was something students could really get excited about as they watched it develop.
"It was a lot of hands-on experience for the students, and it coincided with their science and social studies curriculum," said Vumbaco.
While the Karner Blue lost out to the red spotted purple/white admiral, the Karner Blue might well be called the official Pinewood butterfly.
Like the fifth-grade students who will move on to Draper Middle School next year, the class ceremonially released their classroom pets " a group of Karner Blues " this spring.
Emily Vincent, a fifth-grader, said she's a little nervous to move up to middle school, but that she'll take the lessons she learned in Mrs. Vumbaco's class with her.
"We want to save the Karner Blue's habitat," she said, wearing a T-shirt with a photo of her class on the front. "We want them to always be around.""
