Currently I have 9 Avicularia metallica, all of them are either spiderlings (3rd molt) or juveniles (10th molt). As with many tarantulas, the appearance of the animal changes quite dramatically during its development. Very young metallica spiderlings have light brown legs with dark ends and a copper marking on the abdomen (top picture). Around the 8th molt the color of the legs becomes much darker and pink "shoes" appear (middle and bottom picture). The adult spider will be of blueish-black color and have a blue metallic shine, hence the scientific name of the species.
Just one molt later the general color of the body has changed to a dark blueis-black hue with the tips of the legs turning light pink. These four pictures show the evolution of the typical metallica color. During subsequent molts the color will darken even further with the copper red markings on the back disappearing and a metallic blueish sheen appearing. Of course I will post these pictures here as I take them.
