Rowan found these owl butterfly eggs in the Pavilion. This is the only species they breed on site. All other chrysalises are imported and they don't have caterpillar host plants in the green house.
This photgraph also won an Honorable Mention in the Lifecycle catagory of the Butterfly Pavilion's 2005 Photo Contest. I have to admit that I made my final choice based upon the early entries that were posted on the walls of the entry hall. I didn't see any egg photos, so I figured this had a chance to be noticed.
