“…Spiders may use chemical cues in prey detection or recognition of favorable or unpalatable prey types, or even in predator recognition [Persons and Uetz, 1996a, b;Punzo and Kukoyi, 1997;Persons et al, 2001]. Many spider species produce chemical compounds for social recognition [Krafft, 1982;Pollard et al, 1987], as well as species recognition and reproductive isolation [Jackson, 1987;Costa et al, 1997;Barth, 2002]. Spider pheromones are most often deposited by females in, or on, silk (e.g., webs or draglines) which attracts potential mates and may release male courtship behavior even in the absence of all other cues Rovner, 1980, 1982;Suter and Renkes,1982;Roland, 1984;Barth, 1993;Schulz and Toft, 1993;Costa et al, 1997;Trabalon et al, 1997].…”

Spiders perceive the world using multiple sensory modes, including vibration, vision, and chemical senses, for prey detection and communication. These sensory modes are used in many communication contexts, either individually or in multimodal signaling. Selection for effective signaler-receiver communication and species discrimination is especially strong for these predatory and potentially cannibalistic arthropods, resulting in the evolution of considerable diversity in signaling behaviors. In this paper, we review sensory mechanisms involved in spider signaling and present an overview of recent work done on wolf spiders (Lycosidae) that use multimodal communication (simultaneous visual and vibratory signals) in sexual signals during courtship. The relative importance of visual and vibratory signaling modes, and the use of multiple modes varies among closely related species in the genus Schizocosa, providing a model system for investigating multisensory guidance of complex behavior. Here we examine previous and current research on responses of female spiders to components of male courtship behavior, using several experimental techniques including cue isolation (single sensory modes), video/audio digitization and playback, and cue-conflict (mixed conspecific/heterospecific components) to tease apart elements of multimodal signaling.

“…Courtship is traditionally viewed as an intersexual communication mechanism (Krafft 1982;Robinson 1982;Peretti et al 2006) acting during the entire mating process, providing the stage for species recognition (Costa and Capocasale 1984;Costa et al 1997;Jackson and Pollard 1997;Simó et al 2002), mate choice (Fernandez-Montraveta and Schmitt 1994) and cryptic female choice (Eberhard 1985;Eberhard 1996;Peretti et al 2006). Some authors assume that sexual behavior differences among spiders, mainly during courtship, are the first and most efficient mechanism of reproductive isolation, with clear influence on evolutionary histories and speciation patterns (Costa and Capocasale 1984;Foelix 1996;Miller et al 1998).…”

Nuptial gifts and sexual behavior in two species of spider (Araneae, Trechaleidae, Paratrechalea)

Male delivering of a prey packed in silk as a nuptial gift is rare in spiders and restricted until now to Pisauridae. Here, we describe this behavioral pattern found in two Trechaleidae species, Paratrechalea azul Carico 2005, and Paratrechalea ornata (Mello-Leitão 1943), mainly based on field observations. We observed the following steps of sexual behavior: sperm induction, nuptial gift construction, mate searching, pre-copulatory courtship, copulation, and copulatory ending. In this group, a nuptial gift consists of a prey wrapped in silk, which appears as a white rounded shape. The male carries his nuptial gift in his chelicerae while searching for a female. When he finds a female, he shows a stereotyped courting behavior consisting of a hyperflexed posture that is also assumed by the receptive female while they face each other. The copulatory position and pattern is similar to that found in other Lycosoidea: the male mounts the female and makes a total of four palpal insertions while alternating sides. However, after each palpal insertion the male dismounts and returns to a frontal position while biting the gift. Copulatory courtship is evidenced by palpal and leg movements. The copulation ends by female initiative and she almost always retains the nuptial gift. No case of pre-copulatory or post-copulatory cannibalism has been recorded. Descriptions of nuptial gift construction by males and copulation in these species, as well as hypotheses about the origin of nuptial gift construction among spiders, are presented. These descriptions are the first records of such nuptial gift offering for Neotropical spiders and for non-Pisauridae species as well.

“…In recent years there has been increasing interest in the size and complexity of animal display repertoires (Hartshorne 1973, Otte 1974, Wilson 1975, Barlow 1977, Smith 1977, Andersson 1980, Craig & Jenkins 1982, Krafft 1982. Moynihan (1970) defined major displays as being qualitatively distinct from others in the species' repertoire, each having some characteristic peculiar to itself alone.…”

Intraspecific interactions ofHoloplatyssp. indet., a New Zealand jumping spider (Araneae: Salticidae)

The display repertoire of Holoplatys sp. indet. is unusually large and complex for a salticid spider. Approximately 27 major displays occur, a number comparable to the maximum repertoire sizes recorded for vertebrates and social insects. Males have 3 different mating tactics, the one used depending on the female's maturity and location. With adult females outside nests, males use 'type l' courtship; this is shown experimentally to be a form of visual communication, and includes specialised movements of the legs and palps. With adult females inside nests, males use 'type 2' courtship; this does not depend on vision, and includes elements such as probing and palpating on the silk while outside, and tapping and brushing the female after entering the nest. With subadult females, males first use type 2 courtship and then spin an adjacent silken chamber and cohabit. After the female moults and matures, mating occurs inside her nest. Post-mount courtship is a non-visual phase that precedes copulation and occurs as a component of each tactic. Females, subadults, and juveniles display also, and different combinations and sequences of displays occur, in accordance with the sex/age class and location of each interacting spider. One display of females, 'thumping', has an unusually pronounced releaser effect on male mounting behaviour. Although well fed spiders never killed displaying conspecifics, they frequently killed and ate ones that failed to display. Starved spiders, however, often killed displaying conspecifics. A hypothesis is advanced to explain the effectiveness of displays in protecting spiders from cannibalism. The functions of displays are discussed.
