Description
The green lynx spider Peucetia viridans (Hentz 1832) is the largest and commonest member of the family Oxyopidae, with a distribution throughout the southern United States, Mexico, and Central America (Brady 1964). It is a cursorial hunter that forages on prey commonly found on plants (Arango et al. 2000). Although little studied up to 1960, P. viridans has been the sole or partial focus of at least 25 papers since then, making it one of the best-characterized hunting spiders in North America. While much is now known about the reproductive biology of P. viridans, one question that remains unresolved is whether adult females ever remate in the wild. This is especially significant given that P. viridans and P. longipalpis F.O. Pickard-Cambridge 1902 are the only oxyopids known to produce copulatory plugs (Suhm et al. 1996), structures which are commonly thought to delay and/or reduce the probability of female remating (Eberhard 1996). Brady (1964) was the first to note the presence of plugs in P. viridans females, as he found that the two openings of a mated female's epigynum were usually plugged with a hard, black material, often with the two-pronged distal portion of the paracybium of a male palpus inserted in each opening and embedded in the material. Brady stated that the black material must be deposited during or immediately after insemination, a suggestion possibly corroborated by Whitcomb & Eason's (1965) observation during a laboratory study of a large drop of shiny liquid on the epigynum of a female immediately following copulation that later disappeared.
