WAYNE — The Kennebec Land Trust has announced the dates and speakers for its 17th annual conservation lecture series. This year’s program is “Maine Insects: Ecology & Conservation.” The annual March lecture series is modeled after the early New England lyceums that began in 1826 in Massachusetts, which for many years hosted lectures, debates and concerts for public audiences. The trust’s annual Lyceum Lecture Series is supported by Gloria and Lincoln Ladd and this year’s series is sponsored by the Maine Entomological Society. All programs are free and open to the public and are held at the Ladd Recreation Center in Wayne.
