Spinybacked Orbweaver

Female Spinybacked Orbweavers (Gasteracantha cancriformis) are one of the spider species with spines that stand out.

 

There’s a visible difference between the females and the males of the species. It’s the females that have the long abdominal projections commonly known as spines as males lack them or have very short spines.

 

6 red spines are seen on the dorsum of the female Spinybacked Orbweaver in Florida and the Southeast. Black spines are seen on the female Spinybacked Orbweaver in other states and areas of North America.

 

The main color of the spider is white. Additional black dots are seen along the body of the spider between the spines.

 

In rare cases, Spinybacked Orbweavers can also be yellow with either red or black spines.
