Defaecation 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 کاملFunction of bright coloration in the wasp spider Argiope bruennichi (Araneae: Araneidae).
There are two major competing explanations for the counter-intuitive presence of bright coloration in certain orb-web spiders. Bright coloration could lure insect prey to the web vicinity, increasing the spider's foraging success. Alternatively, the markings could function as disruptive camouflage, making it difficult for the insect prey to distinguish spiders from background colour variation. ...
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 کاملPhylogeography of a good Caribbean disperser: Argiope argentata (Araneae, Araneidae) and a new ‘cryptic’ species from Cuba
The Caribbean islands harbor rich biodiversity with high levels of single island endemism. Stretches of ocean between islands represent significant barriers to gene-flow. Yet some native species are widespread, indicating dispersal across oceans, even in wingless organisms like spiders. Argiope argentata (Fabricius, 1775) is a large, charismatic, and widespread species of orb-weaving spider ran...
متن کاملThe Influence of Vibratory Courtship on Female Mating Behaviour in Orb-Web Spiders (Argiope keyserlingi, Karsch 1878)
Web-building spiders are important models for sexual selection. While our understanding of post-copulatory mechanisms including sperm competition and cryptic female choice is considerable, our knowledge of courtship and how it influences male and female mating decisions is still extremely poor. Here, we provide the first comprehensive description of male courtship behaviour and vibrations gener...
