Rather than using a web, adult females catch their prey by using a line with one or two sticky drops (a "bolas") which they swing.

Two are arranged in the centre of the cephalic (head) part of the cephalothorax, the larger behind the smaller.

[1][5] The genus Ordgarius has been placed in the broadly defined subfamily Cyrtarachninae,[6] and, as a bolas spider, would be expected to fall within the informal group of mastophorines, although not included in the molecular phylogenetic study that defined this group.

Adult females place a few horizontal lines of silk between twigs or leaves and then hang their bolas from it.

There is evidence to suggest that, like related genera, Ordgarius can produce a mimic of the sex pheromone used by a female moth to attract a male.
