I was at Rainbow Lake, Sanders County, about 10 miles NE of Plains. This rocky substratum lake had dozens of nymphs of Leptophlebia cupida under every rock. I have never seen such numbers of this species.

Reproductive Characteristics
The adults began to swarm about 1:30 PM 5/17/2010 and I have attached the first photo I have ever taken of this species.

Threats or Limiting Factors
All forms of stream quality degradation pose potential threats. These include siltation; pollution from agricultural and industrial waste; and hydrological alteration from drainage, dams, or withdrawal of excess water for human use.
