- 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.
