[3] This spider spins a moderately large (can be about 20 cm long in diameter) and very tightly coiled web.

M. gracilis is unique in appearance due to its large spiky abdomen and black and white bodies.

[1] These spiders tend to wander and rarely ever remain in the same web site for more than week.

They tend to like moisture; they are more easily found in woodland forests that are near a lagoon, pond, or other small bodies of water.

One study mentioned that these spiders were found in an area that tends to flood during their mating season.
