Black Spinybacked orb weavers: Identification.
Black Spinybacked orb weavers (Gasteracantha cancriformis) demonstrate distinct sexual dimorphism concerning the size. Females measure 5-9 mm in length and 10-13mm across, whereas males are 2-3 mm long and slightly narrower. All morphs have six abdominal spines; however, the coloration of these may vary from red to yellow or orange depending on location. Additionally, many occasionally boast white spots underneath their abdomens and colored legs.
The ebony coloring of the Black Spinybacked Orb Weaver can be advantageous in nabbing their prey; however, they become more exposed to predation due to their unthreatening pigmentation or design that fails at repelling aggressors.
