Chilobrachys dyscolus , also known as “Asian smokey earth tiger” or “Burma chocolate brown”, is a remarkable and stunning bird spider due to its coloration and anatomy from Myanmar, Malaysia, Vietnam and India (source). Sometimes you’ll notice people talking about the “Vietnam blue”, which is referred to Chilobrachys dyscolus blue form, commonly known as Chilobrachys sp. blue vietnam. This specific species is native to South Vietnam. However the “chocolate” in her common name makes you think different, the spider swaps color from chocolatebrown to black (blue) post-molt. Mother Nature keeps surprising.
