Orb-weaver spiders

Araneus diadematus

Cross orbweaver

This orb weaver often eats its own web at dusk and spins a new one before dawn, recycling the silk's proteins.

WhereGardens, hedgerows and forest edges
SizeFemale 6.5 to 22.5 mm, male 4 to 13 mm body length
WhenJune to October

Body colour ranges from pale yellow to deep brown or almost black, but nearly every adult carries a bold white cross of dots across the top of the abdomen, giving the species its common name. The banded legs and stout, rounded body make it one of the most familiar orb weavers of gardens and hedgerows.

Females rebuild their orb web after dark most nights, eating the old sticky spiral before spinning a new one, then spend the day motionless at the hub waiting to feel a vibration in the threads. After mating, the female produces a single yellow egg sac that overwinters, with spiderlings emerging the following spring.

Similar in size and web building habit, but it carries four bold white spots arranged in a square rather than a cross on the abdomen, and often adds a silk retreat to one side of the web that the cross orbweaver does not build.
