Found on walls near streams. Not a fly at all but another insect order - the Plecoptera.

Plecoptera. I don't see many of these. Only the second species I've stumbled on in three years.

There are apparently many species in good numbers near water. The tiny ones are difficult to find in daylight hours when they hide in vegetation and are seldom seen or photographed. This live specimen was shaken out of vegetation after rain. The insets are in the more normal lateral view. Graini images in low light.

Phone image in B/W. The large (central) wings were 10 mm in length and looked green to the eye against the whitish light. The original image was false color (predominantly blue).

Taton: on the Myanmar border in Northern Thailand on a white LED light over a running river in the early evening. I suspect the light had a UV component. There are apparently ~14,000 known species of Cadisfly, all nocturnal. A white fluorescent or LED light near or over a river in the evening is the only circumstance in which I've seen them.

I am a complete novice with this family having seen only one species in ten years in my local area (Pathum Thani, Thailand), which is crossed by an extensive grid of slow moving canals (Khlongs). Many Cadisfly larva inhabit running water which probably accounts for their relative absence locally.

Taton: on the Myanmar border in Northern Thailand under a light early evening. There are apparently ~14,000 known species. Nocturnal. A white fluorescent or LED light near or over a river in the evening is the only circumstance in which I've seen any of them. Low res'n phone image.

I am a complete novice with this family. Over ten years I have seen only one species in my local area (Pathum Thani, Thailand) which is crossed by an extensive grid of slow moving canals (khlongs). Many Cadisfly larva inhabit only running water which probably accounts for their relative absence locally.
