Some you will encounter more than others, which is why we have prepared this guide to the most common spiders found in Thailand so you can be aware of them.


What Are The Most Common Species of Spider in Thailand?

The Banded Phintella spider, scientifically known as Phintella vittata, is a species of jumping spider found in Thailand.

It has a distinctive black and white banded pattern on its abdomen. Its cephalothorax and legs are predominantly black, with hints of white markings.

The unique banded pattern on the abdomen of the Banded Phintella spider serves as a form of camouflage, blending in with the surrounding vegetation and making them less detectable to predators and prey.

This arachnid is an active hunter and doesn’t build a nest, but hunts on the forest floor. They rely on their incredible jumping ability to capture prey (usually small insects resting under leaves).

They have excellent eyesight and use it to locate and stalk their prey.

2. Black Widow & Brown Widow

The female Black Widows are the most dangerous. They are characterised by their shiny black bodies with a red-orange hourglass print on their abdomen. Male Black Widows are brown, not black, with small red spots.

They are particularly active during warm months, so watch out for the dry seasons from March to May before the rain storms come.
