"Native Bees - an introduction" was the first of a speaker series held at the Lehigh Gap Nature Center. Anita Collins, a United States Department of Agriculture honeybee scientist and a member of the Nature Center board, was the speaker.
She heard that the U.S. Geologic Survey wanted someone to survey bees, which hadn't been done since 1900, and became involved. She had a Power Point presentation to illustrate her talk.
