Fakta

Females can change colour from yellow to white, or back again, to match the flower they sit on. This process can take up to 25 days.1

The spider can catch prey much larger than itself, because its paralysing venom works so well.1

Unlike many spiders, it does not wrap its prey in silk. It relies entirely on venom to hold its meals still.1

Females leave silk trails called draglines behind them as they move, and males follow these trails rather than pheromones.1

Females wait on flowers and do not travel far, while males roam over great distances to look for mates.1

Females live longer than males, on average.1

Pembongkar mitos

Mitos: Because it is a venomous spider with a name like Whitedeath, it is dangerous to people.

Faktanya: The goldenrod crab spider is harmless to humans. Its fangs cannot pierce human skin, and its venom is too weak to harm larger animals.1
