Richard Brown has graciously agreed to give the following zoom presentation
(open to all) to the Austin Butterfly Form early next week.

"Male Sex Scales of Moths -- Natural Wicks for Scent Dispersal -  Monday,
July 26th at 7 pm Central Time
Presented by Richard l. Brown, the W.L. Giles Distinguished Professor
Emeritus as well as Director Emeritus, Mississippi Entomological Museum at
Mississippi State University.

Male Sex Scales of Moths – Natural Wicks for Scent Dispersal Butterflies
and moths have attracted much attention because of their colorful wing
patterns derived from pigments inside their scales. Males of many
Lepidoptera have scales that lack pigments, but rather are used for
producing and disseminating pheromones that are essential for mating
success. This presentation is based on examinations of the male scent
scales of tortricid and gelechiid moths with a scanning electron
microscope. The images of magnified scales have revealed another kind of
beauty with the structural innovations that increase surface area to
improve dissemination as well as different ways of protecting the scent
scales when not in courtship.

Richard L. Brown Bio:
I began collecting and studying microlepidoptera in Arkansas during the
1960’s and obtained my M.S. degree in Entomology at the University of
Arkansas. After serving as a medical entomologist in the U.S. Army at Ft.
Sam Houston, I obtained a Ph.D. at Cornell University in 1980. I was then
employed as Director of the Mississippi Entomological Museum at Mississippi
State University where I also taught courses in Insect Taxonomy, Aquatic
Insects, and Immature Insects. My research has concentrated on morphology
and systematics of tortricid and gelechiid moths and has involved fieldwork
throughout the U.S. and in Chile, Venezuela, New Caledonia, Fiji Islands,
and Thailand. Since my retirement in 2020, I have greatly enjoyed working
full time on moths and manuscripts.
