Mike Halsey is a lepidopterist whose interest in moths dates back to his very early childhood. He is currently working at the Murray-Darling Freshwater Research Centre at La Trobe University in Wodonga. His primary role there is administrative (as the Centre's Business Manager), but based on his interest and experience as a lepidopterist he is periodically engaged by the University's Department of Environmental Management and Ecology to assist both with undergraduate course work and individual student project work. Most recently he assisted with the University's late summer Alpine Ecology course at Falls Creek. For the past 4 years, he has worked very closesly with a La Trobe PhD candidate on a project reviewing the Australian Acentropinae (aquatic moths; Lepidoptera; Crambidae) in both the field and the lab.

He is currently working together with Dr Dough Hilton and Axel Kallies on a project reviewing the Australian Heliozelidae, a family of micro-moths which is well represented in alpine regions of South-East Australia. In his own right, he is currently commencing a project reviewing the Australian Incurvariidae. He is an active field worker, with a particular interest in the early-stage biology of micro-Lepidoptera, a field of study not currently well documented in Australia. He is particularly interested in host-parasitoid relationships.

Before coming to Australia in 1991, in England he was part of an active group of field researchers, working closely with J M Chalmers-Hunt and Bernard Skinner, two of the UK's most influential lepidopterists. At Warwick University he was granted an award from the Lord Rootes Memorial Fund to facilitate an experimental study into the mechanisms by which male Lepidoptera emerge prior to females in a given flight seasons.
