Observation notes: Porch light. Very dark overcast, 58 degrees, and ground soaked from the night rain. Total length 20 mm. For the past week, many Swordsman Darts and Fringed Darts have been swarming together early in the morning around my house front porch light, but this one was at the old storage trailer porch light. On this dart I noticed a difference from others in the orbicular area. There are black squares here surrounded by golden veins.
