We are delighted to invite you to the 15th International Congress of Orthopterology, which will be held in San Martín de los Andes, Neuquén, Argentina, from March 8-12, 2026.
San Martín de los Andes holds historical significance as the founding place of the Orthopterists’ Society in 1976, originally established as the Pan American Acridological Society (PAAS) by 35 orthopterists. Our vision for the 2026 Congress is expressed as “Half a Century Advancing Orthoptera Research and Collaboration.” This congress celebrates the scientific advancements and collaborative efforts made in Orthoptera research and management over the past 50 years, highlighting both the Society’s milestone and its continued dedication to research and partnership.
San Martín de los Andes is a picturesque town located in the Argentine Patagonia, known for its stunning natural beauty. It is nestled on the shores of Lake Lácar and surrounded by the majestic Andes mountains. The town serves as a gateway to the Lanín National Park, home to the iconic Lanín Volcano with endemic Orthoptera fauna from the high Andes and the Patagonian steppes.
We are committed to creating a congress where orthopterists from all over the world work together beyond the border of specialties, whether in research or applied management, to create a unity of knowledge.
We look forward to meeting you in San Martin de los Andes in March of 2026!
