The Flower Spiders are a group of spiders whose common name (as implied) are often found on flowers. They are usually colourful, their colours reflecting the colour of the flowers that they are found on, providing camouflage, against predators such as birds and enabling them to ambush approaching insects.

Some of the Flower Spiders are brownish to green, especially on the carapace and legs, with an abdomen that is white to yellow. The white and yellow colouring suit spiders that like to wait in the centre of flowers, especially for nectar-feeding insects.

Others have abdomens that are variously patterned in red, brown or green. This patterning is thought to help the spiders blend in with the leafy foliage or flowery backgrounds. Some species of Flower Spiders can slowly change their colour to suit their background.

Most Flower Spiders are diurnal (active during the day) and can be quite common on many Australian native flowers including grevilleas and wattles. They are territorial with only one spider per flower(s), although you may see a male and female on the same flower.

Some species from this group of spiders may also be known as “Crab Spiders” or “Flower Crab Spiders”.
