The purpose of this website is to document the species and distribution of mosquitoes collected in Montana. Following the arrival of West Nile virus in Montana in August 2002, mosquito surveillance began through a cooperative project involving Montana State University’s Veterinary Entomology Lab under the guidance of Dr. Greg Johnson and Marni Rolston, Dr. Grant Hokit and Dr. Sam Alvey of Carroll College, and the Montana Department of Public Health and Human Services. The information presented through this website is a result of these monitoring efforts and includes mosquito species collected, yearly and seasonal population dynamics, in-state species distribution, notes on biology and West Nile virus presence.
