Dipterists Society

International Congresses of Dipterology (ICD)

Since 1986, these Congresses have been held every four years in a different location around the world as a means of sharing research and enhancing communication among dipterists on an international scale. For nearly 40 years, these Congresses have been expertly accomplished by the Organizing Committees of each one, under the authority given by the ICD Council, an organization whose purpose is to provide continuity and direction for International Congresses of Dipterology. On 8 May 2025, the Council officially merged with the Dipterists Society, following the unanimous votes of both organizations, so from here on the Council operates as an Executive Committee of the Dipterists Society. This was a long time coming, as the first proposals for the formation of an international society of dipterology which included the Council were made in the 2008 Council meeting, so this merger represents the culmination of this idea.

The next ICD is the 11th (ICD XI), to be held from 10–16 July 2027 at the Westin Hotel in Zagreb, Croatia.

More information will be posted here in the near future!

The ICD webpages have been expertly maintained by Jim O'Hara since 2003, after he was first elected to the ICD Council. This was the first web presence for these meetings, and Jim diligently kept the website up to date even well after his term as a Councilor ended. While the website has long been hosted courtesy of the University of Guelph, the website has changed hands to be hosted hereafter by the Dipterists Society. The last version of that page can be viewed at the archived page for International Congresses of Dipterology, along with other archived captures back as far as the beginning!
