Red and Black Spider Identification in Australia
Red-bodied and black-abdomen spider often found under bark, logs or in leaf litter.
Usually low riskRed and black spiders can trigger concern because of the colour contrast, but many are not redbacks and need shape, web and hiding-place clues checked. A red front body with a darker abdomen under bark, logs or leaf litter points toward a ground-dwelling comparison, whereas a redback is normally assessed with its rounded abdomen and messy web. Do not handle either spider to settle a photo identification.
Quick identification
- Red body with darker abdomen
- Often under bark or logs
- Not the same shape as a redback

What to check next
Compare with redback clues: redbacks are usually in a messy web with a rounded dark body and red abdominal mark.
When to seek medical help
Seek advice for severe pain, allergic symptoms or if redback cannot be ruled out after a bite.

Bark, logs, leaf litter, garden beds and sheltered outdoor spaces.
