SMALLEST SPIDER IN THE WORLD

You will need a magnifying glass to see the image of Patu Digua- the smallest spider in the world.

Patu digua is by some accounts considered to be the smallest spider in the world, with males reaching a body size of about 0.37 mm, roughly the size of the head of a pin. However, there are other spider species of similar size where only the female is known. Because male spiders are usually smaller than females, one can assume that these are even smaller than those of P. digua. It is endemic to Colombia.

Kingdom: Animalia

Binomial name: Patu digua

Patu Digua Habitat and Range
Patu diguas are very difficult to find and study. Researchers Yucheng Lin and Shuqiang Li of the Chinese Academny of Sciences, Institute of Zoology found and described Patu spiders for the first time in Asia. The 2009 report, published in “Zootaxa,” lists the spiders occurring in leaf litter, treetops and caves. Scientists have documented Patu diguas or members of the same genus in southeast Asia, Oceana, the West Indies, the Seychelles Islands and South America.

Web Weaving Behavior
Patu diguas weave tiny webs, presumably to catch their prey. These spiders weave horizontally oriented orbs, and line them horizontally with silk. The center of the orb usually contains a white speck, though this function is unclear. According to a 1987 study by William G. Eberhard, published in the “Journal of Arachnology,” the horizontal strands do not appear to be adhesive. Scientists have not been able to observe a Patu digua weaving its web.
