Peucetia viridans – Green Lynx Spider
Green Lynx spiders, like all others in the Family Oxyopidae, are diurnal, that is they hunt during daylight hours. Their hunts are conducted much like those of the jumping spiders (Salticidae); they roam low foliage looking for prey. Their eyesight is not as keen as the jumping spiders, and they more often use the “wait and pounce” hunting tactic most often associated with the (equally well) camouflaged crab spiders, Thomisidae. Oxyopids of North America are characterized by the presence of numerous large, erect spines on the legs and their erratic and sudden movements.
Lynx Spiders have a very distinct eye arrangement: four on the “face”, two looking sideways, and two on top of the head. P. viridans is the largest lynx in North America. Lynx spiders pose little danger for humans. Although there have been a few cases of human envenomation, the bites do not cause much more than temporary pain and swelling at the site, no more than a honeybee sting. 
Little is known about the chemistry of the venom, but it has been discovered that P. viridans, alone among spiders, is capable of spraying its venom up to 20 centimeters (about 3/4 inch). Nothing is known about the defensive effectiveness of this procedure, or whether the spider also uses it offensively.
Lynx spiders are among the major predators occurring in low shrubs and herbaceous vegetation. Few detailed observations have been made on the feeding habits of lynx spiders, but investigations by W.H. Whitcomb et al. (1963) have disclosed that they are important predators of crop-damaging insects. Oxyopes salticus Hentz, another lynx spider and one of the most common spiders in Arkansas cotton fields, has been reported by Whitcomb et al. as the chief predator of the bollworm, Heliothis zea (Boddie). Peucetia viridans is also an important predator of insect pests of cotton fields. In the field, green lynx spiders have been observed feeding on many species of moths of the families Noctuidae, Geometridae, and Pyralidae, including some of the most important crop pests.
