Physical Description and Identification

Adults

Size: The female spiders are about 15 mm (0.59 inches) long while the males do not exceed 2 mm (09.07 inches) in length.

Other Characteristic Features: No striking or highlighting feature of the spiders belonging to this genus has been noted. However, individual species would have specific identifying traits, like the magnificent spider has tubercles on their head. At the same time, the ordgarius hobsoni also have spiny projections.

Eggs

The egg sacs remain clustered in the brown egg sacs mostly kept amidst foliages. 

Spiderlings

Not much information has been obtained about the spiderlings, though like most other species they too live on their own after maturation.

The Web

Two spiders of this genus, namely, the Ordgarius magnificus and Ordgarius hobsoni, do not generally spin wheel-shaped or spiral webs like other members of the orb-weaver family. They are bolas spiders, capturing their prey by throwing or swinging a bolas (sticky blob attached to one end of a silken line) at them.

Are the Spiders of the Ordgarius Genus Venomous

There is not much detail about these spiders biting, though their venom is not harmless to humans.
