The green lynx spider (Peucetia viridans) is a commonly encountered arachnid. Its striking appearance often sparks concern, but understanding its characteristics and behavior helps alleviate common fears. This article explores the nature of the green lynx spider and its interaction with humans.
Identifying Green Lynx Spiders
The green lynx spider is distinctive. It typically displays a bright, translucent green body, providing excellent camouflage among foliage. Females can reach a body length of up to 22 millimeters, while males average around 12 millimeters. They often feature a few red spots on their abdomen and sometimes a red patch between their eyes.
Their long, pale green or yellow legs are covered with prominent black spines and hairs. Unlike many other spiders, green lynx spiders do not construct webs for catching prey. Instead, they are active hunters found in gardens, meadows, and shrubby areas, often resting on flowers or plant tops where they ambush insects.
Assessing the Danger
Despite their striking appearance and ability to spit venom defensively, green lynx spiders are not dangerous to humans. Their venom, primarily for subduing insect prey, is not medically significant to people. Bites are rare, typically occurring only when the spider feels threatened or is guarding its egg sac.
A bite usually results in localized pain, redness, and minor swelling, comparable to a bee sting. Serious reactions are rare, with no reported local tissue necrosis or systemic symptoms. These spiders are not aggressive towards humans and prefer to flee when disturbed. However, females guarding their bright orange egg sacs can be more defensive and may squirt venom as a deterrent, sometimes up to 8 inches.
Encountering a Green Lynx Spider
When encountering a green lynx spider, observe it from a distance and leave it undisturbed. These spiders play a beneficial role in gardens and agricultural settings as natural pest controllers, preying on various insects including moths, flies, and grasshoppers. They help reduce populations of harmful insects, contributing to a healthier ecosystem.
If an unlikely bite occurs, typical first aid for minor insect bites is usually sufficient. Clean the wound with mild soap and water, and apply a cool compress to reduce discomfort and swelling. Medical attention is rarely needed, unless an individual experiences an allergic reaction, which is a general medical precaution for any insect bite and not specific to this spider.
