Red Admiral and Painted Lady Research Site

Just in time to track the apparent massive migration wave of red admirals, Iowa State is re-launching its Red Admiral and Painted Lady Research Site with new interactive maps tracing the migrations and observations of red admiral and the three ladies — American, painted, and West Coast — among other butterflies.

Here’s the blurb from their site:

Our new map, database, and registration form will soon be available. We are working on getting them installed on our new server.

In the meantime, please send your observations directly to Royce Bitzer at A sample sighting report is available at How to report your observations. This page will also be updated for 2012 and will include new instructions for using the new reporting form.

The previous map is currently unavailable for viewing. Previous butterfly observations from 2001 to 2012 will be available again for viewing once the new map is online.

We are following the ongoing Spring 2012 migration and are collecting observations of migration rates (number seen per hour, or numbers per hour crossing a line transect of defined width such as 50 feet or 100 feet) and prevailing flight directions (either cardinal directions such as N, NNE, NE, etc. or in degrees of azimuth). We are studying 1) how movement of air masses and weather fronts affect Red Admiral movement and final distribution, and 2) the extent to which Red Admiral abundance and migration intensity vary from place to place during the migration.
