“The Dragonfly Whisperer” at the NW Stream Center
August 8 @ 7:00 pm - 8:30 pm PDT
The Incredible Lives of Dragonflies and Damselflies
Dragonflies are fascinating creatures, with a rich heritage of folklore and fables that vary greatly from culture to culture. European cultures tend to see them as dangerous — even deadly. Asian and Native American cultures see them as signs of good luck, longevity, and prosperity. The facts about dragonflies are even more interesting than the fables:
• They have six legs, but don’t walk.
• They have acute vision, but can’t hear.
• They predate dinosaurs, but are going strong today.
• They can spin at 1,000 rpm in mid-flight — the fastest spin in nature.
Scientist-author Jim Walker gives a lively and informative presentation exploring the world of dragonflies on August 8th, 2019 at 7:00 PM at the NW Stream Center. Included are slow-motion videos of a behavior he discovered called the splash-dunk/spin-dry. In this behavior, a dragonfly plows into the water one or more times to bathe (splash- dunk), and then spins at 1,000 rpm to dry off (spin-dry). Professor Walker, known to his friends as “The Dragonfly Whisperer,” will even share tips on how to coax a dragonfly to perch on your finger, and how to see the delightful Happy-face Dragonfly!
Jim Walker earned his Ph. D. in theoretical physics at the University of Washington. He was a professor of physics at Washington State University for almost 20 years and, at the time of his retirement, was the Boeing Distinguished Professor of Science and Mathematics Education. Professor Walker is the author of several university-level textbooks on physics, as well as a recently-published dragonfly field guide, Common Dragonflies and Damselflies of the Pacific Coast. He was also featured on a recent episode of Evening Magazine on King5 television. Professor Walker and his wife Betsy divide their time between Western Washington and Arizona, and enjoy birding and dragonflying in both locations.
