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.
