Metallic Winged Damselfly

Post by svalley »

A tropical damselfly in the family Polythoridae, Cora terminalis from the rainforest on the east slope of the Andes Mts. in Bolivia.

The blue coloration on the wings is an optical affect that can only be seen from certain angles. When the wings are perpendicular to the line of sight they are completely transparent. The males perch in small patches of sunlight along an otherwise heavily shaded stream. When another male enters their territory the two face off and spiral around each other as they ascend up the beam of sunlight. Their wings flash like strobe lights. They also flash their wings open and closed in a display, when a female they have mated with, is ovipositing. This type of non-contact guarding is relatively rare in damselflies.

Nikon F5, 70-180 Micro-Nikkor, f32@160, 2 SB-28 flashes on a custom bracket and gunstock, Elitechrome 100

Thanks Ken. Yeah, I shot a lot of macros, mostly odonates, but a few other insects also.
