D. Elmo Hardy was "one of the last polymaths of Diptera Systematics." Over the nearly 7 decades of active research, Elmo named and described nearly 2,000 species in 34 different families of Diptera. These were published in 437 articles and notes. Elmo may be considered the "father of Hawaiian Dipterology" and has inspired the research of many students of Diptera systematics.
The collection of articles in this volume is a celebration of Elmo's achievements in the taxonomy and systematics of flies from the Asia-Pacific Region.
