In cotton fields of east Texas, the southern black widow spider, Latrodectus mactans (F.), was observed to capture the red imported fire ant, Solenopsis invicta Buren, which constituted 75% of the prey of L. mactans. Remains of workers, queens, and males of S. invicta were found in the spider webs. L. mactans were observed to feed on ants captured in the webs indicating that S. invicta were used as a food source. Juveniles as young as third instar were observed capturing S. invicta workers. In… 

Feeding habits of the brown widow spider "Latrodectus geometricus" (Araneae: Theridiidae) in northern Chile

The results show that in Chile this brown widow Latrodectus geometricus has a polyphagous diet, and point to a positive and significant preference for Elateridae, Curculionidae and Kalotermitidae over other arthropods.

Southern black widow Latrodectus mactans (Fabricius) (Arachnida: Araneae: Theridiidae)

The Southern black widow spider, Latrodectus mactans (Fabricius), is a venomous spider found throughout the southeastern United States and it is believed that sexual cannibalism within the widow species in natural settings is more associated with the male's physical inability to escape rather than the female's interest in consuming him.

Red Widow Spiders (Araneae: Theridiidae) Prey Extensively on Scarab Beetles Endemic in Florida Scrub

Frequency analysis showed that temporal patterns of prey capture by individual spiders were infrequent (≤ 0.4 prey per day) and statistically random, and 5 species of scarab beetles endemic to Florida scrub accounted for 65% of prey by weight even though their numbers were modest.

The diet of the black widow spider Latrodectus mirabilis (Theridiidae) in two cereal crops of central Argentina

A polyphagous diet of this spider species in wheat and oat fields is reported, with ants being the most important prey item, as found in other Latrodectus spiders around the world.

Black widow spiders, Latrodectus spp. (Araneae: Theridiidae), and other spiders feeding on mammals

The success of widow spiders in subduing small mammals can be explained by their ability to spin strong webs made up of tough silk, and producing a very potent toxin specifically targeting the vertebrate nervous system.

Prey analysis of the spider Achaearanea riparia (Blackw.) (Araneae, Theridiidae), a generalist predator in winter wheat fields 1

A comparison of A. riparia with other spiders inhabiting the winter wheat fields showed that, though all spiders studied are generalist predators, the “feeding niche” of A., riparia differed significantly from the others, characterizing A. Riparia as a unique forager within the spider community of the winter Wheat ecosystem.

North American widow spiders (Araneae: Theridiidae)

This work reviews and synthesizes published information on the five North American Latrodectus species, focusing on distribution, ecology, anatomy, physiology, reproduction, ontogeny, behaviour, web structure, silk, venom, genetics, and phylogeny.

The natural diet of a polyphagous predator, Latrodectus hesperus (Araneae: Theridiidae), over one year

Analysis of the diet of a web-building spider in a natural habitat of coastal British Columbia, Canada, shows that L. hesperus is a polyphagous predator that feeds primarily on prey from two orders of insects.

New Record of Two Species of Black Widow Spider in Mosul City (Iraq)

Two species of black widow spiders were recorded for the first time in Mosul city during the summer of 2012 and 2013, both of which are poisonous and dangerous to humans.

Evaluation of the Importance of the Striped Lynx Spider, Oxyopes salticus (Araneae: Oxyopidae), as a Predator in Texas Cotton

Predation by the striped lynx spider, Oxyopes salticus Hentz, on cotton arthropods was studied in an unsprayed field in east Texas to estimate how many prey may have been killed by the spider in the middle of the growing season.
