As the day heats up, says Michael Cheever of the center, they revert to landing with their wings folded vertically. Wear hair spray or the color blue to attract them. Keep an eye out for the Blue Postman. New to the exhibit and native to South America, these longwings are smaller than morphos. They're mostly blue with two stripes of red at the top and two narrow bands of white at the bottom of their wings.
Volunteers are on duty to discuss the flora as well as fauna.
For a quarter, you can pick up a list of appropriate plants for hosting a flying cotillion in your own back yard. Exhibit is in the Dallas Horticulture Center's Blachly Conservatory. Tell us what you think.
