Nature has its fair share of beautiful living beings, there in every shape and color. Spiders, no matter how terrifying they look, sometimes have enchanting red coloration on their small bodies. These little red spiders are relatively common and can be found anywhere around the globe. This time, we’re taking 15+ tiny red spiders worldwide that are unbelievably beautiful to make a list.
For this list, we’re excluding the Clover Mites, commonly referred to and mistaken for small red spiders. We’re taking other spiders from around the world that are tiny and red. Let’s see how the list goes:
15+ Tiny Red Spiders Worldwide
1) Black-Tailed Red Sheetweaver Spider
The very first spider on this list of tiny red spiders is the Black-tailed Red Sheetweaver. The little spiders usually inhabit grasslands, agricultural fields, and lawns. They are bright red in color, with reddish-brown to black legs and a black tubercle on the abdomen.
The black-tailed red sheet weaver gets its name from the particular way it weaves its web. The web is horizontal at the base, with additional webs woven above it. The function of the extra webs is to stop flying prey and cause it to fall on the horizontal sheet.
