Wolf Spiders

Spiders of Victoria series

For most spiders, sons and daughters never get to meet their mum. The spiderlings hatch and are left alone to survive or become prey themselves. One exception to this behaviour is the wolf spiders (family Lycosidae). They provide maternal care that helps to protect the spiderlings until they are older and more able to feed and defend themselves.

The female wolf spider weaves a circular mat of fine silk onto which she deposits a hundred or more eggs. She then weaves silk around the eggs, draws up the sides of the mat and sews it into a silken ball. The size of this silken ball is often about the same as the spider itself.

Using strong silken threads, she then attaches the egg case to the under surface of her abdomen and carries it with her. She incubates the eggs during the day by facing the egg case towards the sun and slowly turning it. When the spiderlings finally hatch, they crawl up onto the mother’s abdomen, often covering her several layers deep.

Her maternal care extends only to providing the spiderlings with transport and protection from predators. The spiderlings do not share any of the prey that the mother catches, and if they fall off they are not rescued. Still, it’s a better start to life than most other spiderlings receive.

The wolf spider is not alone in the maternal care department. Scorpions also carry their young on their back, and female huntsmen spiders will also protect their spiderlings.

Hi Joel, there are many species of wolf spider; some construct burrows but many species can be found in leaf litter or are known as vagrants, that is just using whatever shelter they find. As it notes in the sheet above the female wolf spiders construct an egg sac and carry it around with them while they are hunting for food, sometimes 'sunning' it. It is quite common to see these spiders walking around with the egg sac. It's even better to see the female walking around with all her young on her back.

Have had a burrowing variety in my lawns for many years, sometimes with a slik covering over their hole but this would only be about 10% of those noticed. Have seen eggsacks attached to the abdomen and also babies covering the abdomen. do not appear as aggresive either freezing or scurrying down their burrows when they spot me.

Spotted a wolf spider on the side of the alpine walking track not far from falls creek.I photographed it as we did not know it's species. It was promptly identified by the museum discovery centre with a detailed reply as a wolf spider.
