Spiny Orb-web Spider

Gasteracantha falciformis


Species was about 1cm long and about 3cm wide. The males are generally much smaller than the females and commonly lack the showy coloring of their fairer sex. They often spin their own smaller orb web near an outlying portion of the female's.


A crop field near the University of Agriculture in Morogoro, Tanzania.


I found three of this kind of spiders, but this was the only one of which the color combination was so beautiful.

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!

Wild spider! Fabulous photo!
Nino, If you ever make it further north into east Africa, please consider adding your beautiful spottings to the mission East African Biodiversity. You will need to look at the map to see if the area you found them is covered as I couldn't cover all of East Africa.
