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

  • In adult males, the front pair of legs have more black and are thicker/heavier than the rest.
  • Females and juveniles may be mistaken for a member of the genus Platycryptus because of the similar coloration and habitat. Adult males may be mistaken for Plexippus paykulli, but the stripes are different.
  • Researchers have seen this species taking down moths that were easily twice the spider’s weight (Robinson & Valerio 1977). The spider may hold the moth in its jaws and drop down on a drag line while it waits for it to become subdued by the venom.
  • Egg sac is lens-shaped and houses 25-40 eggs. The sac is placed inside a silken retreat where the female spider guards it.
