The Redback Spider (Latrodectus hasseltii) is a notorious arachnid native to Australia.
This small but potent spider has earned its reputation for its venomous bite, though the good news is that serious bites are rare.
The Redback Spider is a member of the widow spider genus (Latrodectus), which also includes the infamous Black Widow.
It’s easily recognizable by the striking red stripe that runs down the back of the female’s abdomen, resembling an hourglass.
Let’s take a deeper look at the redback spider.

Female Redback Spiders are significantly larger than males.
Females typically measure about 1 centimeter in body length, while males are much smaller, only about 3-4 millimeters long.
Redback Spider Webs

These messy, tangled creations often resemble a spider’s attempt at abstract art!
You’ll find these haphazard webs tucked away in cozy hideaways like under rocks, logs, and piles of firewood.
And don’t be surprised if you discover a Redback Spider web lurking in a quiet corner of your garage, shed, or even inside your home (depending on where you live).
They’re masters at finding secluded spots to spin their webs.
