Arrow-shaped Micrathena

Micrathena sagittata is a species of spider belonging to the family Araneidae. It is found in the eastern United States and throughout Central America.

This is a striking spider with a distinctive arrow-shaped abdomen which is largely yellow, with black depressions above and variable red and black patterning below. Males are up to 5 millimetres (0.20 in) in length (excluding legs), but females are much larger at around 9 millimetres (0.35 in). The males lack spines.

They leave a hole in the center of their web to assist in motion.
