What is the Smallest Spider in the World?

February 14, 2024

Spiders are probably the most misunderstood creature in the insect kingdom. They often get a bad reputation for being creepy, scary and sometimes downright dangerous. The truth is that, with few exceptions, they are harmless to humans. Spiders can actually be beneficial to our environment as they consume many insects that are harmful to us, like mosquitoes and caterpillars.

While a lot of people try to kill spiders when they see them in their homes, it is much better to take a closer look at these amazing creatures and maybe even release them. To do that, all you need is a glass and a lid.

In the following article, you will find out what is the smallest spider in the world. The smallest known spider belongs to the family Symphytognathidae and is named Patu digua. Adult females of this species reach only 0.37 millimeters in length – that’s smaller than the head of a pin!

Other extremely tiny spiders include the Samoan moss spider (Maevia inclemens). This delicate arachnid inhabits humid areas such as moss, and it is one of the most fascinating creatures on earth. It has an incredibly well-developed nervous system, which covers about 80 percent of its body. It’s also a master of camouflage, and it can tremble its entire body to make itself invisible in the dark. It can even hide behind its moss-covered legs! Another tiny arachnid that may be considered the smallest in the world is the Anapistula ataecina from West Africa. Males of this species are even smaller than female Patu diguas and are reportedly smaller than the head of a pin!
