Beatriz Coelho is a bee person, degree in 1985 from the University of São Paulo, completed a Masters in 1994 studying social behavior of Augochloropsis iris (Halictidae), and her PhD in 2001 doing the systematic revision of Augochlorella (Halictidae). She was managing the bee collection of the Museu de Zoologia da USP (MZUSP) from 1996 to 2006. Recently, she moved to Manaus (Amazon State, Brazil). For many reasons it would be very difficult for her to continue studying bee systematics in Amazon. She had already decided to study micro-Hymenoptera, but was not sure about which group. She was invited by Dr. Alexandre Aguiar who introduced her to the project. It was exactly what she was looking for.
