The Academy of Natural Sciences of Drexel University will be featured in a six-week online campaign to save Pennsylvania’s Top 10 Endangered Artifacts. An innovative experiment in nonprofit crowdfunding and community building, the campaign launches today and continues through midnight of November 1. The public is encouraged to support the conservation of two important 18th-century butterfly specimens through voting, sharing and donating at

The ancient butterflies, so fragmentary that only one of the two can be identified with certainty, represent the oldest insect specimens known to exist in the Americas. Historical letters indicate an American diplomat shipped the specimens from Malta to the American Philosophical Society in Philadelphia in 1841, nearly a century after they were collected. They were given to the Academy in 1864 and had been preserved between sheets of mica, a naturally occurring, clear mineral that predated the ready availability of fine, thin glass for the purpose. Using mica to serve as glazing represents a very creative preservation technique, according to Academy Entomology Collection Manager Jason Weintraub, who co-authored a paper on the subject in the 2013 Proceedings of the Academy of Natural Sciences of Philadelphia. “It is noteworthy that the Academy, Philadelphia and Pennsylvania hold the only examples of this method known in the Americas.”

The butterfly fragments themselves cannot be restored, but conservators will construct special housing for each specimen and a storage container that will prevent light and temperature fluctuations from causing further deterioration. Preserving these fragmentary specimens is important for the potential information they could provide scientists. Should it prove possible to extract and sequence DNA from these specimens in the future, scientists may be able to confirm their identity, determine their precise geographic origin, and obtain other clues about the history of these specimens. “Natural history specimens are potential powerhouses of information that could lead to information about evolution and environmental change through the millennia,” said Weintraub.

Pennsylvania’s Top 10 Endangered Artifacts, a statewide initiative created by the Conservation Center for Art & Historic Artifacts – the largest nonprofit conservation center in the country – began in January with a statewide call to nonprofit institutions in the Commonwealth of Pennsylvania to submit artifacts demonstrably in need of conservation. An independent review panel of collections care professionals chose the top 10 artifacts from 60 submissions, based on their historical and cultural significance and need for conservation.

“The Academy of Natural Sciences is thrilled to be a part of this special project,” said Dr. Ted Daeschler, the Academy’s Vice President for Collections. “As a 200-year-old natural history museum with 18 million plant and animal specimens, the Academy is a leader in preserving and studying nature’s bounty.”

“Our goal with this campaign is to showcase the state’s historic treasures and the need to preserve and protect our heritage for future generations,” says Ingrid Bogel, Executive Director of CCAHA. “We’ve created this program to give institutions a new platform through which to share their stories and to give people a chance to show their support by voting as many times as they’d like, sharing their favorite artifacts with friends through social media and supporting the conservation of these artifacts with online donations.”

Voting begins on Thursday, September 19 and ends on Friday, November 1 at midnight. At the conclusion of the campaign, institutions that meet their fundraising goals will begin the conservation process, and the artifact garnering the most votes will be named the winner of The People’s Choice Award.

Pennsylvania’s Top 10 Endangered Artifacts is supported by The Pew Center for Arts & Heritage and by The Beneficial Foundation. The project is part of CCAHA’s Save Pennsylvania’s Past initiative, a multi-year, statewide effort to protect and preserve the millions of objects and historic artifacts that shape the Commonwealth of Pennsylvania’s history and define our nation.
