The spiny orb-weavers (Gasteracantha cancriformis), are colorful spiders found in different colors like orange, white, and yellow with spines and spots on their back.The females always have six pointed spines on their shell, but the shell color is either white, yellow or orange, and the spines are either black or red. Males are smaller and do not have spines. The spiny orb weaver spins flat, round shaped webs in shrubs, trees, and in the corners of windows and similar outdoor areas of buildings.The web captures flying, and sometimes crawling, pests such as beetles, moths, mosquitoes, whiteflies, and other small fly species.
