Illustration of Brown Drake Mayfly (Ephemera simulans)

The Brown Drake is a large mayfly with mottled brown wings and three long tail filaments, famous among fly-fishers for producing intense, brief emergences on warm early-summer evenings. The burrowing nymph lives in soft stream sediments for 1–2 years. Spinner falls after mating can cover the water surface with dying adults, triggering explosive fish feeding.

Habitat
Clean streams and rivers with soft sediment and gravel
Diet
Nymphs: algae and organic sediment. Adults: do not feed
