These larvae were in a thin film of water on a vertical rock face near tree line (1400m) on the slope of Mount Washington, New Hampshire, USA on June 8, 2011. Size is 5-6 mm. I assumed they were diptera but did not find any family they might be. I hope I'll find them again next year and get better pictures.  In situ:  |

My guess would be Psychodidae

I hadn't thought of Psychodidae. It doesn't look much like the common drain fly (Clogmia albipunctata). The guide to American aquatic insects says they do live in rock seeps and have secondary segmentation, which appears to be present here. |

Although a psychodid was my first impression too, I cannot see the head, so perhaps some Atrichopogon-species may be possible too? |
