Phidippus audaxHentz of varying ages were field-collected and observed for feeding on a range of commonly occurring insects. Insects offered to the spiders included crop pests, economically unimportant species, and insect predators. Twenty insect species previously unreported as prey ofP. audaxwere found to be consumed by spiders of various ages. In addition, late-instar and adultP. audaxwere presented with a series of paired insect prey choices and their feeding behavior was observed. The spiders were found to attack prey selectively, with some species being attacked and consumed readily, whereas others were avoided and still others were only taken occasionally. The coccinellids,Hippodamia convergensGuérin-Méneville andColeomagilla maculata(DeGeer), were generally avoided, butGeocoris punctipes(Say) was readily attacked and consumed by the spiders. Similarly, bollworm,Heliothis zea(Boddie), larvae were attacked and consumed significantly more often by the spiders than adults of the boll weevil,Anthonomus grandisBoheman.
