Role of structural requirements in web-site selection in Cyrtophora cicatrosa Stoliczka (Araneae: Araneidae)
Cyrtophora cicatrosa weaves a three-dimensional dome web and is commonly found in thorny bushes and cacti. The factors that could be responsible for this selection were studied, both by field observations and laboratory experiments. Structural requirements in terms of space availability were found to be an important factor in the selection of the web site, though other factors could be signific...
متن کاملDefaecation behaviour of Argiope aurantia (Araneae: Araneidae)
We examined the defaecation behaviour of Argiope aurantia both in natural situations and in a greenhouse. The spiders defaecated more frequently at night than during the day. The nightly pattern of defaecation was not related to time of feeding. A. aurantia displayed at least two distinct behaviours related to defaecation, one of which involved leaving the web. These results are discussed in re...
متن کاملCoy Males and Seductive Females in the Sexually Cannibalistic Colonial Spider, Cyrtophora citricola
The abundance of sperm relative to eggs selects for males that maximize their number of mates and for females that choose high quality males. However, in many species, males exercise mate choice, even when they invest little in their offspring. Sexual cannibalism may promote male choosiness by limiting the number of females a male can inseminate and by biasing the sex ratio toward females becau...
متن کاملBourgeois behavior and freeloading in the colonial orb web spider Parawixia bistriata (Araneae, Araneidae).
Spiders of the tropical American colonial orb weaver Parawixia bistriata form a communal bivouac in daytime. At sunset, they leave the bivouac and construct individual, defended webs within a large, communally built scaffolding of permanent, thick silk lines between trees and bushes. Once spiders started building a web, they repelled other spiders walking on nearby scaffolding with a "bounce" b...
متن کاملAge-related sequential web building in the colonial spider Metepeira incrassata (Araneidae): an adaptive spacing strategy.
Colonial orb-weaving spiders provide insight into the proximate mechanisms by which social animals space themselves within a group. We examined mechanisms for the temporal patterns of web building that determine individual positions in Metepeira incrassata (Araneidae) colonies. The spiders display a characteristic age-related sequence of daily web building, with larger spiders completing their ...
