Hope Stonebridge, 3, carefully checks out the spider collection that was part of the “Insect Safari” that came to the Freeland Library on Thursday. Don Ehlen brought his traveling collection of creepy-crawlies to South End libraries — including a scorpion that glows under UV light — and dozens of children learned about the life of bugs during the visit by the Seattle-based insect expert. The visit was sponsored by the Friends of the Clinton, Freeland and Langley libraries.
