Editing Jumping spider (section)

=== Courtship and mating behavior ===

Jumping spiders conduct complex, visual courtship displays using movements and physical bodily attributes. A form of [[sexual dimorphism]], the males possess plumose hairs, colored or iridescent hairs (particularly pronounced in the [[Maratus|peacock spiders]]), front leg fringes, structures on other legs, and other, often bizarre, modifications. These characteristics are used in a courtship "dance" in which the colored or iridescent parts of the body are displayed. In addition to displaying colors, jumping spiders perform complex sliding, vibrational, or zigzag movements to attract females. Many males have auditory signals, as well. These amplified sounds presented to the females resemble buzzes or drum rolls.<ref>{{cite journal|title=Seismic signals in a courting male jumping spider |pmid=14555743 |doi=10.1242/jeb.00634 |year=2003 |last1=Elias |first1=DO |last2=Mason |first2=AC |last3=Maddison |first3=WP |last4=Hoy |first4=RR |volume=206 |issue=22 |pages=4029–4039 |journal=The Journal of Experimental Biology |doi-access=free |bibcode=2003JExpB.206.4029E }}</ref> Species vary significantly in visual and vibratory components of courtship.<ref>[[Rebecca Morelle|Morelle, Rebecca]] (2 May 2008) [http://news.bbc.co.uk/2/hi/science/nature/7378196.stm " Study sheds light on spider sex"], ''BBC News''.</ref> The ability to sense UV light (see Vision section) is used by at least one species, ''[[Cosmophasis umbratica]]'', in courtship behavior,<ref>{{cite journal | last1 = Lim | first1 = Matthew L.

If receptive to the male, the female assumes a passive, crouching position. In some species, the female may vibrate her [[pedipalp|palp]]s or abdomen. The male then extends his front legs towards the female to touch her. If the female remains receptive, the male climbs on her back and inseminates her with his palps.<ref name="Foelix">{{cite book|title=Biology of Spiders|first=Rainer F.|last=Foelix|publisher=Oxford University Press|year=1996|pages=[https://archive.org/details/biologyofspiders00foel/page/195 195–197]|isbn=978-0-674-07431-6|url-access=registration|url=https://archive.org/details/biologyofspiders00foel/page/195}}</ref>
