Andrew D. Warren, Ph.D.

Andy Warren conducts research on the systematics, biogeography, biodiversity, ecology and evolution of butterflies and moths, with a focus on skipper butterflies (family Hesperiidae), in collaboration with students and researchers worldwide.  An updated list of Andy’s publications can be found here.

Andy was the Senior Collections Manager at the McGuire Center for Lepidoptera and Biodiversity, Florida Museum of Natural History, University of Florida, from January, 2010 to September, 2023.  Currently, Andy is located in Castle Pines, Colorado, focusing his energies on his family and planning for extensive fieldwork across the western USA in coming seasons.

If you’re a butterfly fan, check out the Butterflies of America website, a collaborative effort Andy initiated in 2008 which has developed into the world’s largest and most comprehensive collection of butterfly images.  More information on Andy can be found in this interview, as well as in stories about some of his recent discoveries, including the Pink-spot Sulphur Butterfly in Florida, a new genus of skipper from Jamaica, and a new Owl Butterfly from Mexico.

One of Andy’s ongoing research projects involves investigating the chemical mimicry system that certain spiders have evolved to attract male moths, so they can eat them!  More information on this to come…
