Speaker Bill Toone, the director of ECOLIFE, is a conservation biologist and spokesperson who hasn’t missed a Mexican monarch migration in 25 years. The iconic monarch butterfly is a true marvel of nature. It weighs less than a penny, yet it makes one of the longest migrations on Earth across a continent, with pinpoint navigational accuracy, to a secluded place it has never been! Join the monarchs' perilous and extraordinary journey while following an intrepid scientist’s 40-year search to find the monarchs’ secret hideaway. The first Monday of the month, seniors 65+ enjoy the Science Center exhibits, a lecture and an IMAX film at a discount. Noon lecture; 2PM IMAX film. 619-238-1233.
