Dear colleagues, As evolutionary biologists, you will find ECE 2026 particularly rich this year, with several thematic sessions dedicated to evolutionary processes, adaptation, phylogenomics, the evolution of symbioses, and insect-environment interactions. Many symposia are tailored to showcase cutting-edge research on diversification, evolutionary mechanisms, and integrative approaches that bridge molecular, ecological, and comparative perspectives. We warmly encourage you to explore these sessions and contribute your latest insights to help shape a vibrant evolutionary biology program. The XIII European Congress of Entomology (ECE 2026) is approaching fast, and we are thrilled by the enthusiasm already growing across our community. As we prepare to welcome you to Tours, France, from 29 June to 3 July 2026, this is a friendly reminder of two important deadlines: Only one month left! Early bird registration closes on 15 December 2025 Take advantage of reduced registration fees by completing your Early Bird registration before 15 December 2025. Abstract submission also closes on 15 December 2025 You are invited to submit your abstract to one of the 50 scientific symposia, grouped into 10 main thematic sessions covering the full breadth of entomology from evolutionary biology and ecology to biodiversity, applications, and emerging challenges. In addition to the designated symposia, we warmly welcome contributions relevant to each thematic session that do not fit into any specific symposium. A dedicated category is available for this purpose in the submission system.
