The accompanying video features the northeastern North American subspecies Habronattus calcaratus maddisoni. The trinomial honors Wayne Maddison whose research and teaching have been a primary force in expanding our knowledge of jumping spiders. He has authored and applied new analytic tools designed to clarify salticid relationships as part of his work to expand our understanding of salticid phylogeny in general. Maddison has conducted field work in Africa, Asia, and South America, and is involved in various ongoing educational efforts focusing on his favorite group of spiders. As with many accomplished biologists Maddison’s fascination with jumping spiders began in his childhood. Habronattus calcaratus maddisoni is the eastern subspecies ranging south from New England to the Cumberland Plateau and north to the Great Lakes. Griswold, 1987: 139; Map 9: 332.
