I just read up on them and, yes, although seldom, they will bite. The bite is suppose to be painful but is non-venomous.
The females reach .87 inches while the males are smaller (just less than 1/2 inch). They are considered to be a somewhat beneficial insect as they prey on moths and their larvae - including the bollworm, cotton leaf worm and cabbage looper moths. They do, however, also prey on honeybees
They are listed as North America's largest lynx spider. I am just glad I spotted him before dead-heading!
