... Now we have very cold nights (below 32F), but still see occasional mayflies that home-in on our kitchen lights. Is it possible for mayfly populations to continue to propagate in the winter?
The most prolific winter insect hatches are midges. They emerge from Hot Creek and the Owens River both above and below Crowley on most sunny winter days. Winter mayflies include the "blue winged olive" mayflies. Look at the fishing reports on winter fishing sites such as sierradrifter.com for the mentions of "BWOs".
