Abstract submission is now open! Abstracts should be submitted via this word document. Then email to Ros Sparrow


To give adequate time for comprehensive content and questions, regular presentation slots will be 20 min long (including questions). Recommended: 15 min talk + 5 min question period.

Slots for invited plenary speakers are 40 min long (including questions). Recommended: 30 min talk + 10 min question period.

Morning and afternoon refreshment breaks will be of 30 min and lunch breaks 90 min duration to facilitate networking and discussion.

Presentations should be uploaded to this Dropbox link ahead of time (preferred) or to the session computer on the morning of your talk. Further instructions will be available at the registration desk if required.

Presentations should be either a PowerPoint (.ppt or .pptx) or an Adobe PDF (.pdf) file in wide format (16:9) if possible. If applicable, video files should be embedded or should be included as separate files.

Congress programme

There are five main themes of the ICO2023 (see descriptions below). But the congress is also open to other topics such as dragonfly ecology, evolution, behaviour, physiology and all other aspects concerning dragonflies.

Dragonflies on islands (Host Andreas Martens, Germany)

For odonates, islands offer opportunities and limitations. On one hand, there is the limited population size, the limited range, the high risk of extinction and the strong impact of habitat destruction and invasive species under island conditions. On the other hand, islands offer good opportunities for radiation and speciation. Secondly, islands may be resorts for endemics or act as stepstones for invaders, especially under climate change conditions. The third perspective is that islands may serve as good models for trends in population size, habitat use, threads and extinction risks, worldwide. Because of isolation and clearly defined land size, it is easier to gain complete data sets, especially in the tropics

Biogeography (Host Vincent Kalkman, The Netherlands)

Understanding distribution patterns: Data on distribution and phylogeny of dragonflies and damselflies has increased steadily in the past decades.  With this data we can start to better describe and understand diversity patterns. How does habitat choice shape distribution patterns? Which distributions can best be explained by present day climate and which reflect past geological events? How will climate change impact the odonates of Cyprus?

Taxonomy and Phylogeny (Host Jessica Ware, USA)

The intra-ordinal relationships among dragonflies and damselflies will be covered in this session on the taxonomy and phylogeny of Odonata. Both molecular and morphological systematics have been in a sort of renaissance over the last few years as new genomic and morphological tools have become available. We welcome talks on revisionary taxonomy, systematics, divergence time estimation, phylogeography and presentations which use phylogenies more broadly. 

Conservation (Host Geert de Knijf, Belgium)

Many species of dragonflies are declining and are threatened in many parts of the world. To halt their decline and to restore their habitat it is crucial to know their habitat requirements both for the larval as for the adult stage. In this session we welcome presentations on habitat requirements, including their terrestrial habitat, on restoration project, on population monitoring and trends.  

Dragonflies in a changing climate (Host Frank Suhling, Germany)

There is no doubt that various aspects of climate change particularly warming and drought are affecting dragonflies in several ways. In this session we want to explore all aspects of climate change that may affect dragonfly distribution, life cycles, behaviour, species interactions, and community composition. We welcome presentations on field and laboratory studies exploring effects for instance on changes of development and phenology, on interactions between species, or on interactions between warming, drought and other stressors. Also trends in the development of dragonfly populations and major changes in the distribution of species that may be associated with climate.
