Maevia - Blog Posts
Went out somewhere new yesterday and was lucky enough to bump into both forms of Maevia expansa male! Top images are the "tufted" morph and bottom are the "gray" morph.
They look absolutely nothing alike, and both males even use different courtship rituals to attract females! Like I've said before, the easiest way to differentiate this species from the much more common M. inclemens is to look for the bold white markings around the eyes of M. expansa, which are displayed in the pictures I have provided. The white is very bright and obvious, which makes distinction very easy, especially since jumpers love to look at you head-on!
Jumping Spider (Maevia expansa), female, taken May 8, 2025, in Georgia, US
A curious jumper making her way along a twig! She was not very happy with me but ultimately cooperated enough to get a single good picture. Like the Dimorphic Jumping Spider (Maevia inclemens), this spider's males have two different morphs: a "gray" morph that is gray with black stripes and bright orange palps and a "tufted" morph that is black with white legs and 3 black tufts of hairs above its eyes. The males of the species look nothing alike, which may cause them to be misidentified. This species can be differentiated from M. inclemens by the presence of white patterning on the head of the female and around the eyes of the males. You can also use locality, as they have currently only been found in Georgia and once in Tennessee.
