On 9 July 2011, a WDA symposium was held in Leiden, the Netherlands, in lieu of the larger WDA symposium which had been planned for 2011 in Japan and which had been postponed because of the earthquake damage there. Brachytron grabbed the occasion and managed to secure an interview with Dr. Rosser W. Garrison, who with his wife Dr. Natalia von Ellenrieder are considered the authorities on the Odonata of Central and South America.
