Research Interests

Through Dr. Rozen’s worldwide research on the biology, immature stages, and evolutionary relationships of bees (Hymenoptera: Apoidea), the AMNH houses what is believed to be the most complete collection of bee eggs, larvae, and pupae worldwide. Since 1949, Dr. Rozen has conducted fieldwork in the United States, Europe, Trinidad, Republic of South Africa, Namibia, Egypt, Morocco, Turkey, Brazil, Chile, Venezuela, Israel, Pakistan, Mexico, Argentina, Peru, the former Soviet Republic of Kyrgyzstan, Costa Rica, and China. Dr. Rozen has focused on the comparative biology and systematics of solitary and cleptoparasitic taxa. He is currently working on research projects pertaining to the structure and adaptive function of bee cocoons, particularly with respect to those of leaf-cutter bees (Megachilidae). The results of his research through the years have been reported in more than 150 papers.

Please contact Dr. Rozen if you are interested in borrowing apoid Hymenoptera or visiting this part of the collection.
