Identification
Adult males and females are similar to other Pelegrina, and may be distinguished from most by the face markings in males and abdomen markings in females.(1)

The markings of adult males are nearly identical to those of Pelegrina peckhamorum(1), so as with most spiders proper identification may require detailed examination of genitalia.
Male:
Female:
Habitat
Often found in dense shrubs near wooded lots.
Life Cycle
Both sexes have identical markings until the male reaches subadult stage and becomes just slightly darker.
Remarks
Cleptoparasitic behavior was observed in one adult male, carefully clipping food from the web of an unidentified sheetweb spider.(jb)
