The spider reinforces the simulation of bird-droppings by drawing its legs close to the body and lying motionless on a leaf for long hours.

It sometimes sits on a small patch of white silk, which can be mistaken for the white stain caused by the bird-dung when it is splashed on the leaf. Some Phyrnarachne spiders emit a pronounced smell of faeces or urine. The sight and smell of bird-dropping may be a clever device to attract and ambush flies.

Crab spiders move sideways, like crabs.

Spiders lay their eggs in egg sacs. These sacs are made out of woven silk and help to protect the eggs and maintain the right humidity.

Spider egg sacs vary greatly in size, shape, and colour ( most of them are cream, brown, or white )

The egg shape depends on the spider species, some are:

• round ball,
• a disc with a rounded part in the middle
• squishy pillow
• fluffy mass of silk

The egg sac silk protects the eggs against physical damage and excessive drying, wetting or heating, as well as provides a shield against predators like ants and birds

One egg sac can have  4 to 600  eggs

When the eggs hatch, they are known as spiderlings. These spiderlings are usually small and pale in colour.

The eggs of many spiders are glutinous and stick together allowing them to be laid in a continuous stream into the partly built silk egg sac
