Everyone got a chance to net and tag butterflies as well as record data. Lynn McBride of The Nature Conservancy's San Antonio office and her daughter Ashley helped to photograph the event. Two slide shows were given. David Larson, of the National Park Service gave a short program on monarch tagging techniques. Jackie Poole, Texas Parks and Wildlife botanist, gave a slide show on her recent trip to Africa.
Monarch butterflies are the only animal to make a multi-generational migration.
They begin their journey in Mexico where they mate and winter over. Approximately 100 million monarchs hibernated there last year. Beginning in February, they begin their journey into the United States heading due north. As soon as the female finds a milkweed plant she will lay eggs on it and then die. Those eggs will hatch and the next gen-eration will fly further north laying eggs along the way.
