This little guy, more formally known as Theridion grallator, is native to the Hawaiian islands. It grows to a length of about five millimeters. On The Island of Maui, the patterns tend to be hereditary, but on the other islands they appear to change based on the spider's diet. Given their small size, as well as their ability at hiding during the day, they aren't a major prey item on anyone's menu. The purpose of their coloring is still unknown.

ReplyDeleteIf they hide during the day, then I'm assuming they're out at night. So their coloring may be a way to scare off nocturnal predators especially if it gives off a luminous glow. Or perhaps it needs a lighter color to soak up as much vitamin D as possible. Just tossing out ideas.
ReplyDeleteSo this spider actually has a happy face? No Photoshop, right? Very very strange, but happy! :-D
ReplyDeleteCorrect, no photoshop.
