Cyclosa argenteoalba, in the trashline orbweavers genus, is a species of orb weaver in the spider family Araneidae.

C. argenteoalba frequently relocate to different places to build a new webs until a location with a significant amount of prey is found.

They are born with a completely silver dorsal abdomen and change color to include some black as they mature.

[3]Cyclosa octotuberculata is a close relative of the C. argenteoalba, and these two spider species are commonly found in Japan in similar habitats.

A suggested hypothesis for why it still exists is that the silver color could help regulate temperature by cooling down the spiders that are exposed to direct sunlight.

The female coloring difference is most likely not a factor in mating, since male spiders have poor vision and instead rely on pheromones.

Webs are usually constructed during the day,[4] and the process frequently begins in the morning and stops in the evening.

[9] C. argenteoalba often relocate and rebuild their webs if they determine that a location does not have a significant amount of prey.

A unique characteristic of C. argenteoalba is its use of "long-lasting memory" to enhance its foraging efficiency during web relocation.

In other words, the rate of web relocation in response to low prey capture is lowered when the spider uses its past foraging experience (i.e. its "long-lasting memory").

[10] They may also relocate due to higher incidences of conspecific interactions in prey abundant areas.

Their behavior contrasts from their close relative C. octotuberculata, who bring previous debris to their new webs.

This was determined through experiments where spiders produced longer silk decorations when there was an increased predation risk, but was not affected by the amount of available prey.

Web decorations reflect ultraviolet light, which birds and insects that prey on C. argenteoalba are sensitive to.

Typically, they will reproduce in May, August, and sometimes October, and during these times their body mass is at its seasonal peak.

After females have laid their eggs, their abdomens are noticeably smaller, which makes their reproduction easier to study.

These characteristics lead to a larger investment in reproduction in order to counteract the lower survival rate of the species.

C. argenteoalba also show a more prominent reduction in clutch size the second time they lay eggs in a year compared to the first.

They do this by detaching the female's scape, which is their genital appendage that the male must grab to position itself and is necessary for successful mating.

One common example of parasitoid larvae often found on C. argenteoalba are polysphinctines such as Reclinervellus nielseni, which are a type of wasp.

Even though the parasites' manipulation appeared quickly and was long-lasting, the spiders were eventually able to revert to their normal web-building some time after the larvae were removed.

[13] Phylogenetic analysis showed C. argenteoalba is closely related to Hypsosings pygmaea and Areneus ventricosus.
