Dirk Ahrens during an expedition
in the Himalayas, June 1998.
  

Dirk Ahrens' research interests are evolution, phylogeny, and biogeography of melolonthine scarab beetles as well as faunistics and ecological problems of water beetles and Scarabaeoidea. He is currently working on the taxonomy and systematics of Asian Sericinae, with special emphasis on the Indian and Indochinese subregion.
