Physical Description and Identification

Adults

Size: The average size of female velvet spiders range from 0.47-0.59 in (12-15 mm), although the figure might vary, depending on each species.

Color: Bright colors like black, brown or sometimes gray are observed on almost all species. Ladybird spiders have an orange-colored body with black spots.

Other Characteristic Features: The hair is so glossy and thick that it looks like velvet, and hence the name velvet is given. Also, female spiders of this family exhibit genital plate, forming subgroup entelegyne spiders.

Eggs

Female velvet spiders lay eggs in a sac.

Spiderlings

Spiderlings take some time for incubation, and when they come out, their mother’s tissues had already been broken down. The young spiders follow matriphagy by consuming the corpse of their mother.

The Web

The velvet spiders make webs, cluttered with the debris of herbal stuff and sand. The web is similar to a silken tube made of wooly silk, sizing around 3.9 in (10 cm), tucked inside burrows or crevices.

Are Velvet Spiders Venomous

The velvet spider is not likely to be venomous for human. However, there is a possibility that it has some venom, potent for killing insects.
