Observed in the LISDOLA trails. Not sure which Orbweaver spider this is. Looked similar to yellow Spiny Back Orbweaver but bigger, almost an inch. Somewhat triangular but not as much as the google images of an Arrowhead Orbweaver. Couldn’t find match for markings either.
This fly was super excited to join our Native Plant class at Clear Creek Natural Heritage Center. It stuck around for the whole lecture.
