Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

Hi All- found this bug on my car today after a very productive day out on the Big Flatbrook River in Northwestern NJ. Picture not as focused as I’d like but I’m hoping someone can help me Identify this Mayfly??
Thanks

Hi Jersey Boy-
Focus of photo notwithstanding, I believe this male imago to likely be Maccaffertium ithaca.
