In species where virgin females have higher reproductive value to males than nonvirgin females, selection will favour males that can discriminate female reproductive status. Similarly, while virgin females may actively seek to attract males, nonvirgin females may seek crypticity after mating if copulation is costly. Here we show that Australian redback spider males, Latrodectus hasselti, discriminate female maturity and mating status based exclusively on web-borne chemicals. Male activity on… Expand
Mated Redback Spider Females Re‐Advertise Receptivity Months after Mating
TLDR
The results are consistent with the idea that females strategically alter pheromonal advertisement, but cannot distinguish this from the hypothesis that female receptivity arises from chemical manipulation by males. Expand
Male preference and female cues: males assess female sexual maturity and mating status in a web-building spider
TLDR
The data suggest that females signal sexual receptivity and that males are able to discriminate both sexual maturity and mating status, however, males do not exert strong preference for virgins. Expand
Male adaptations to minimize sexual cannibalism during reproduction in the funnel‐web spider Hololena curta
TLDR
It is shown that the funnel‐web spider, Hololena curta, has 3 adaptations that minimize risk to males during courtship and mating, and enhance reproductive success. Expand
Do male guppies distinguish virgin females from recently mated ones?
TLDR
It is suggested that male guppies assess female behavioural and olfactory cues to determine female virginity and then use different mating tactics depending on the female's status, and that the changes in male mating behaviour increase male reproductive success. Expand
Silk-mediated male courtship effort in the monandrous wolf spider Pardosa astrigera (Araneae: Lycosidae)
TLDR
The results suggest that P. astrigera males can discriminate females using chemical cues from silk that has been previously occupied by other males and to older females with higher sexual receptivity, whereas they invest less to silk cues from virgin females regardless of their post-maturation ages. Expand
Male black widows court well-fed females more than starved females: silken cues indicate sexual cannibalism risk
TLDR
The prediction that web-based chemotactile cues of recent female foraging success influence male courtship in the black widow spider, Latrodectus hesperus is tested and it is found that males courted well-fed females significantly more than they did starved females. Expand
Alternative mating tactics in a cannibalistic widow spider: do males prefer the safer option?
TLDR
It is suggested that web-borne volatile cues, typical of adult females, may be reduced or lacking in late subadult females, yet less volatile cues may indicate receptivity. Expand
Male mate choice in a sexually cannibalistic widow spider
TLDR
It is suggested that older females produce more pheromone to attract males and that males are thus misled into mating with older, more aggressive and less fecund females. Expand
Contact pheromones mediate male preference in black widow spiders: avoidance of hungry sexual cannibals?
TLDR
It is concluded that sex pheromones alone can provide information about recent female feeding history, possibly reducing the costs of males expressing choice in the field. Expand
Male reproductive decision is constrained by sex pheromones produced by females
TLDR
It is found that males chose and displayed more courtship behaviour in the silk thread from old virgin females (OV), however, males did not show any preference between silk thread of YV versus ORM females, and there were no differences in courtship behaviours. Expand

Mutual Mate Assessment in Wolf Spiders: Differences in the Cues Used by Males and Females
TLDR
Whether males could detect the mating status of the female and if chemotactile cues from the female played a role in that process were determined and quantified conspicuous aspects of the male courtship to determine if courtship intensity was related to female choice. Expand
Changes in male mate choice in a sexually cannibalistic orb-web spider (Araneae: Araneidae)
TLDR
Male mate choice was affected by male reproductive status: while virgin males strongly preferred penultimate and virgin females to mated females, mated males were apparently indifferent to females of different mating status. Expand
Investigation of potential male mate choice in a monogamous spider
TLDR
Testing for male mate choice with respect to female body weight and reproductive status in a three-choice arena system and compares these findings to field data on male visits at female sites in a marked population suggests that virgin females emit a pheromone that cues male courtship. Expand
SEXUAL CONFLICT OVER MATING IN A SPIDER: INCREASED FECUNDITY DOES NOT COMPENSATE FOR THE COSTS OF POLYANDRY
TLDR
It is shown that polyandry is costly for females despite the production of larger clutches and suggested that multiple mating results from male manipulation of female remating behavior. Expand
Discrimination of airborne pheromones by mate- searching male western black widow spiders (Latrodectus hesperus): species- and population- specific responses
TLDR
Results show that male western black widow spiders are attracted to females' webs by an airborne cue released from the web, can distinguish between conspecific and heterospecific females, and can discriminate between webs produced by conspespecific females from different geographical populations. Expand
Chemical Signaling in a Wolf Spider: A Test of Ethospecies Discrimination
TLDR
These experiments support the characterization of S.~ocreata and S. rovneri as ethospecies reproductively isolated only by female discrimination of species-specific male courtship, and indicate that chemical, but not mechanical cues associated with silk are critical for eliciting male Courtship in both species. Expand
THE MALE MATING SYSTEM IN A DESERT WIDOW SPIDER
TLDR
It is suggested that large males of L. revivensis that mature in spring maximize reproductive success by mating with virgins, and late males will gain greater reproductive success from mating with large, late-maturing females, but the scarcity of these females in the population at this season may make opportunistic mating with non-virgin females a viable strategy.

Information content of female chemical signals in the wolf spider, Schizocosa ocreata: male discrimination of reproductive state and receptivity
TLDR
Male wolf spider Schizocosa ocreata clearly possess the ability to assess reproductive status as well as age-related potential receptivity of conspecific females based on cues associated with silk. Expand
Female-enhanced male competition determines the first mate and principal sire in the spider Linyphia litigiosa (Linyphiidae)

  • Behavioral Ecology and Sociobiology
  • 2004
TLDR
Two to five days before sexual maturation, female sierra dome spiders (Linyphia litigiosa: Linyphiidae) undergo a transformation in their behavior toward males that visit their webs, a system whereby females enhance male-male competition and boost the expected fighting prowess of the principal sire of their progeny. Expand
Limited mating opportunities and male monogamy: a field study of white widow spiders, Latrodectus pallidus (Theridiidae)
TLDR
It is suggested that low encounter rates with females, coupled with high intrasexual competition, drives the evolution of a strategy of high investment by males in a single mating, as was observed in the white widow spider. Expand
