Ant-Mimic Spider Identification in Australia
Small spider that resembles an ant, often with a narrow body and quick ant-like movement.
Usually low riskAnt-mimic spiders are easy to overlook because their narrow body shape and quick stop-start movement imitate ants. Check carefully for eight legs and a two-part spider body before deciding it is an ant; a close photo may also show the large forward-facing eyes typical of many jumping-spider mimics. They are usually seen moving over plants, bark, fences or ground rather than sitting in a capture web. Treat the ant-like shape as a starting clue and compare it with other small active hunters when the image is not close enough for a confident species call.
