During
his 30 years at the INHS, Don has developed an interest in
a wide range of insect groups. His major interest is in the
systematics of the lower brachycerous Diptera, in particular
the families Rhagionidae, Solvidae, Athericidae, Vermilionidae,
and Xylophagidae. He has produced faunal surveys of the Mecoptera
and Tabanidae of Illinois and is currently finishing separate
studies on the winter stoneflies of Illinois, the biota of
Illinois caves, and the biota of Illinois springs in relation
to water quality.
Don
also collaborates with Mike Irwin in the systematics of the
Therevidae of the World, and has published several revisions
of the North and South American therevids in the past six
years. Keys to genera published by Don and Mike are becoming
available on-line. |
