[edit] Description
The female reaches a body length of 22mm, the more slender male averages 12mm. There usually is a red patch between the eyes, with red spots over the body. The eye region is clothed with white appressed hairs. The legs are green to yellow, with very long black spines and covered with black spots. It is rather similar to P. longipalpis, the other Peucetia species to occur in the US.
Amendment: Though the author of this article states that the female may reach a maximum length of 22mm, an approximately 47mm species of this spider was spotted awaiting its prey in a Bird of Paradise plant in Lakewood, California in 2004, and sitting atop the plant blossom was the entire length of the flower. Presenting a non-aggressive behavior and did not move during its roughly 30 minute observation, this spider was not captured and disappeared within an hour of initial observation.
Gravid females are able to change their color to fit their background. This takes about 16 days.[1]
[edit] Habits
The female constructs one to four 2cm egg sacs in September and October of 25 to 600 bright orange eggs each, which is guarded. She usually hangs upside down from the sac and attacks everything that comes near. The eggs hatch after about two weeks. Then it takes another two weeks until fully functional spiderlings emerge. They need eight instars to reach maturity
[edit] Human interest
It very seldom bites humans, and its bite is harmless. This spider is primarily of interest for its use in agricultural pest management, for example in cotton fields. They have been observed to hunt several moth species, including some of the most important crop pests, for example the bollworm moth Heliothis zea, the cotton leafworm moth Alabama agrillacea and cabbage looper moth Trichoplusia ni. and their larvae. However, they also prey on beneficial insects, for example honey bees.
[edit] Distribution
This species occurs in the southern United States, Central America, the West Indies and Venezuela.
[edit] Name
The species name is derived from viridis "green".
It is not to be confused with P. viridana, a species that only occurs in India and Myanmar, or P. viridis from Spain and Africa.
