Thiania bhamoensis is iridescent green-blue. Females are more green, males more blue. Female's face are black. And the males are white.

These spiders build a silken retreat by binding a pair of green leaves together, where they rest, moult and lay their eggs, which is unusual for a jumping spider. Making a single rivet to attach the leaves takes about half an hour. About four to ten rivets are arranged in a roughly elliptical manner. These nests are built by both sexes and juveniles. Although T. bhamoensis can be found on many kinds of plants, it most often chooses Crinum asiaticum (spider lily).

The white elliptical egg sacs are about two to three times the size of the spider and are attached inside the nest.

Twelve different displays were identified during fights between males, including pushing, possibly to assess the weight of the other male.

This species are found from Burma to Sumatra including Borneo Island.

They are called Fighting spider because two males will readily fight each other.

Commonly known as "fighting spider" in South-east Asia. A common belief is that the darkest males are most aggressive.

The species name of this spider literally means "From Bhamo", referring to Bhamo, a city in northern Burma
