The Vanessa Migration Project is a citizen science program that has been active since April 2001 as part of the Red Admiral and Painted Lady Research Site. Citizen observers in North America report their sightings of date, location, flight direction, and other activity of four butterflies of the genus Vanessa (V. atalanta, V. cardui, V. virginiensis, and V. annabella). Objectives include 1) monitoring butterflies and their yearly seasonal distribution; 2) tracking migrations and outbreaks; and 3) studying effects of weather and climatic patterns on butterfly activity.
