I'm fascinated by a wide-range of arthropods, but especially fond of ants and beetles. For my doctorate I am examining harvester ants (Pogonomyrmex spp.) ecology. Over the past decade I have done many investigations into ground-dwelling arthropod communities using pit traps around the SW US. These projects have lead me into the photography and identification of many groups, and most of my photographs here are from my research collections. I seek to curate my specimens in museums, mainly the Colorado Plateau Arthropod Museum of Biodiversity, Forest Entomology Museum at Northern Arizona University, and Museum of Northern Arizona. I am fortune to work in an understudied area and greatly appreciate the help the bugguide community has provided me over the years, which has contributed to many range-expansions, records of rare specimens new to bugguide, and even a new ant species!

New ant species, Strumigenys superstes:

Third known locality of a rare cave-dwelling louse:
