Another Butterfly Presentation

This morning, at the Tilden Botanic Garden, Andy and I gave a presentation for the Women's Chemist Society. As usual, people were fascinated by the video and the live specimens. I had done a bit of research on chemicals as they relate to butterflies, but we mostly talked about rearing and gardening. A docent for the Tilden Garden was there and suggested that we do a class for them. They are booked for this year, but maybe next year.
