Or, cross spider. It is an orb-weaver spider found in Europe and North America. • Individual spiders' colorings can range from extremely light yellow to very dark grey, but all have mottled white markings across the dorsal abdomen, with four or more segments forming a cross. • The markings are formed in cells filled with guanine, which is a byproduct of protein metabolism. • Adult females range in length from 6.5 to 20 mm, while males range from 5.5 to 13 mm. • Occasionally, the female will eat the male directly after mating. • The legs of orb-weaver spiders are specialized for spinning orb webs. • The webs are built by the larger females who hang head down in the center of the web or remain hidden in nearby foliage, with one claw hooked to a signal line connected to the main orb, waiting for a disturbance to signal the arrival of prey. • Prey is then quickly bitten and wrapped in silk before being stored for later consumption. • The initial bite serves to paralyze the prey, and minimize the danger of the spider herself, being stung or bitten. And the enzymes thus injected, serve to begin liquefaction of the prey's internal structures. • Alongside the use of the web to capture other prey, the spiders are also cannibals and prey on each other. However, this only happens before, during, or after mating. • A cross spider is a reclusive creature, and only bites humans if cornered or otherwise provoked. • It responds to a disturbance by vibrating rapidly in its web until it becomes a blur, a reaction that is assumed to confuse potential predators. • *The info was taken from Wikipedia.
