Description

Zillions of these were flying (and dying) along the lakeshore of Granger Lake at Willis Creek Park. The body length on these was on the order of 2 cm. A quick glance through BugGuide suggests that these are probably Hexagenia bilineata.

Description

Large (10-12 mm or so), whitish body, clear wings.

Description from Wikipedia

Mayflies or shadflies are insects belonging to the order Ephemeroptera (from the Greek εφημερος, ephemeros = "short-lived" (literally "lasting a day" "daily" or "day-long"), πτερον, pteron = "wing", referring to the brief lifespan of adults).
