在10个月的时间内分析了oxyopid，Peucetia viridans的天然饮食。这是一个广食性的捕食者，在现场记录的189个猎物项目有65种猎物。主要食性种类有膜翅目、双翅目、半翅目、鳞翅目和直翅目。同种代表的第四大猎物物种，但种间捕食被发现B E相对罕见。猎物组成的物候分析表明，随着时间的推移，主要猎物类群有很大的变化。每月的猎物组成可能反映了相对猎物的可用性。成年雄性在野外觅食的百分比与成年雌性没有显着差异。猎物大小与捕食者体型大小呈极显著相关。
Natural diet of the oxyopid, Peucetia viridans, was analyzed over a ten month period . This spider i s a euryphagous predator ; of the 189 prey items recorded in the field there were 65 species of prey . Major diet items included species of Hymenoptera, Diptera, Hemiptera, Lepidoptera and Orthoptera . Conspecifics represented the fourth major prey species, but interspecific predation was found to b e relatively rare . Phenological analysis of prey composition indicates that there is a large change in majo r prey taxa with time . Monthly prey composition probably reflects relative prey availability . The per cent of adult males feeding in the field was not significantly different from that of adult females . Pre y size exhibited a highly significant correlation to predator body size .
