The latest show at the Hygienic Art Galleries is exploring an unusual art-exhibit topic: How the world’s honey bee population is drastically dropping. This disappearance of honey bees would have a major impact on food production and its related economies, and all of that is being examined in “Colony Collapse,” which opens Saturday with a reception from 7 to 10 p.m. Exhibit curator Jamie Pearson says the art focuses “on the life and death of honey bees in the state of Connecticut, most specifically to address concerns of colony collapse disorder and the many other challenges for survival...” On view will be pieces ranging from drawings by Katie Fogg to an installation and sculptural work by Amy Hannum. “Colony Collapses” runs through May 21 at the galleries, 79 Bank St., New London; (860) 443-8001.
