Identification Traits

Disclaimer: The following table provides a quick overview of the spider's basic attributes. The physical traits are greatly generalized in order to aid in the identification and sorting of spider species using our search feature. This information is not exhaustive, and keep in mind that traits such as color, markings, and overall size and shape can vary widely within a species due to variables such as the spider's age, gender, diet, hydration level, climate, and habitat. Though experienced arachnologists and hobbyists can often classify spiders rather accurately based on their unique markings and general appearance, it's important to know that scientifically accurate spider identification relies on detailed taxonomic keys and microscopic examinations of a spider's reproductive organs.

Additional Remarks

  • The white cross marking is created by collections of guanine under the spider’s cuticle. Rarely, it may be lacking entirely.
  • Underside of abdomen with central black area framed by pale ‘L’-shaped brackets (but lots of other orbweavers have similar ventral markings, as well).
  • This species is one of the most well-known spiders in the whole world, and has been the subject of numerous scientific research papers.
  • It was elected as the “European Spider of the Year” in 2010.
  • In 1952, it was the star of a short film documentary called “Epeira Diadema” by Italian director Alberto Ancilotto. It was nominated for an Oscar in 1953.
  • Spider may “bounce” up and down in the middle of its web if it feels threatened.
  • Egg sacs roughly 20mm in diameter, made of fluffy yellowish-orange silk. Usually stuck in rolled up leaves, under eaves of buildings, within woodpiles, or other protected places, but not hung in the web itself. May contain 100-800 yellow eggs.
