Colourful orb-weaving spiders, Nephila pilipes, through a bee's eyes.
Many orb-weaving spiders in the tropics forage in open sites during the day and some of them have both bright and dark colourations. The conspicuous UV-reflective colour markings of these spiders have been reported to be attractive to visually oriented prey and thus could increase the spiders' foraging success. Using a combination of field and laboratory studies, we examine whether or not the b...
متن کاملEffects of grassland succession on communities of orb-weaving spiders.
Native grasslands are among the most imperiled of the North American ecosystems, but abandoned agricultural areas may provide suitable habitat for animal taxa that are endemic to grasslands. We studied how species diversity of orb-weaving spiders was influenced by secondary succession of a grassland plant community by monitoring the abundance and species diversity in study plots that were culti...

متن کاملOrb Webs in "non-orb Weaving" Ogre-faced Spiders (araneae: Dinopidae): a Question of Genealogy
Observations of web spinning behavior in Costa Rican Dinopis sp. reveal the same behaviors synapomorphic for orb weavers: specifically frame, radius, non-sticky spiral construction, and sticky spiral construction, as well as more detailed motor patterns. Dinopids are therefore highly derived orb weavers, although the behavioral data do not conclusively indicate whether they are more closely rel...
متن کاملThe allometry of CNS size and consequences of miniaturization in orb-weaving and cleptoparasitic spiders.
Allometric studies of the gross neuroanatomy of adults from nine species of spiders from six web-weaving families (Orbicularia), and nymphs from six of these species, show that very small spiders resemble other small animals in having disproportionately larger central nervous systems (CNSs) relative to body mass when compared with large-bodied forms. Small spiderlings and minute adult spiders h...
