Common Candy-Striped Spider

Fascinating facts about the Common Candy-Striped Spider

• This spider wraps its eggs in silk so thick and white it looks like a pearl — then sits guard over it for weeks without eating, starving herself to protect the clutch. The egg sac is often mistaken for a tiny golf ball caught in garden vegetation, which is exactly the point: predators skip over what looks like something inedible.
• A candy-striped spider's web is a masterpiece of triage. She builds an orb web just 15–20 centimetres across, small enough to fit in a teacup, yet dense enough to catch insects ten times her own body weight. The sticky silk costs her enormous energy to produce, so she rebuilds only the damaged sections each night, not the whole structure — a pattern of repair that saves her roughly 30% of her nightly silk budget.
• The name 'candy-striped' is misleading: the colours are not stripes but spots and patches of white, yellow, and brown daubed across an abdomen the size of a pea. This pattern isn't decoration — it's camouflage. Against lichen and bird droppings on garden stems, she vanishes completely, invisible to wasps that hunt spiders three times her size.
• Female candy-striped spiders are cannibals with standards. After mating, she doesn't always eat the male — only if he's small, weak, or poorly fed. Scientists watching wild populations found that well-nourished males escape alive about 70% of the time. She's not being kind; she's being practical: a healthy mate is worth keeping around for a second clutch.
• These spiders survived the last ice age in tiny pockets of southern Europe, then recolonised northward as the climate warmed — a migration that took roughly 10,000 years. Today they're found across Europe and North America, having arrived in the New World via ship cargo in the 1800s. A garden spider's global range is a record written in human trade routes.
