Lasiodiamesa Kieffer, 1924

The larvae of this northern-occurring genus are thought to occur in bog habitats ( Hamerlik et al. 2019; Saether & Andersen 2013). In southwestern Alaska we found larvae inhabiting slightly acidic first-order streams.

Wirth & Sublette (1970) collected adults of Lasiodiamesa tenebrosa (Coquillett, 1905) in Northern and Central Alaska. These collections included a single female of L. tenebrosa collected in a car-top trap ( Sommerman & Simmet 1965) that sampled a 16-mile-long section of Highway 1 between Johnson Lake and Soldotna in mid-August 1965. The other specimens were an adult male and a female collected in Umiat, Alaska in late June 1947 by K.L. Knight. We collected a Lasiodiamesa larva in Central Alaska, south of Manley Hot Springs on a small tributary to the Zitziana River and in a small tributary to Six Mile Lake in Nondalton.
