Like other species in the genus Habronattus males have a Habronattus oregonensis males have an anatomical modification of the foreleg to enhance the visual aspect of their forelegs during a display. In this case, a segment of the foreleg swollen and is mostly bare of bristles, so it shines in the sun.

We took these photos on an exposed rock face near a parking area called Double Parking on the Hurricane Ridge Road. We haven’t seen this species elsewhere.
