Physical Description and Identification

Adults

Size: 1-5 cm (0.4-2 in)

Color: Most species of this genus are either black or brown.

Other Characteristic Features: Their carapaces are glossy, with little hair on them.

Eggs

Females lay their eggs in a burrow. They take a few weeks to hatch.

Spiderlings

Soon after hatching, spiderlings begin to leave their original burrow to build their own nests. After 5-7 years, those who survive become sexually mature and start mating.

The Web

They use their webbing to build tripwires outside their hollows, which alerts them to prey.

Are the Spiders of the Hadronyche Genus Venomous

The venom of these spiders is potentially deadly to humans resulting in illness, severe injury, or even death in case of severity. Hence, antivenoms developed in 1980, following which there have been no records of human fatalities from their bites.

Quick Facts

Lifespan Up to 20 years
Distribution Australia
Habitat Rotting trees and rock crevices
Common Predators Birds, marsupials, rats, reptiles
Diet Insect larvae and wood-eating beetles
