Neoscona domiciliorum Spider Description
Overall, the patterns and colors of N. domiciliorum are very similar to the spotted orb weaver (Neoscona crucifera). N. domiciliorum are usually identified by the stronger colors and contrasts of the bright-colored marking on the back of their abdomen. Also, the part of the legs closest to the body are bright red in colors, giving them their common name “red-femured spotted orbweaver”.
As all spiders in the genus of Neoscona, these spiders have longitudinal grooves on the carapace which separates them from the species in the genus Araneus.
Males are smaller than females in size. Males are about 1/3″ (8 mm) long, while females can be up to 3/4″ (16 mm) long.
These spiders build their large orb-shaped webs in trees and shrubs vertically. These webs are usually created by females and replaced daily by building them during dusk or before daybreak.
Neoscona domiciliorum spider bite
Like most spiders, these orb-weaving spiders are not medically significant and not known to cause harm to humans when biting. They are very hesitant to bite and in the rare cases in which a bite occurs, symptoms are usually comparable to a mild bee sting with some localized swelling and redness.
