Ecology and Evolution of Loxosceles surca

We are happy to report on the ecology and evolution of Loxosceles surca, a close relative to its sister species, L. laeta. Unlike the “tramp” sister species that associates with human habitations, L. surca lives in harsh, dry, and elevated natural habitats in northern Chile. The specimen pictured here was collected at an elevation of over 3,500 meters. We speculate on the ecological prerequisites that allow for adapting to live in human habitations.
