Hello Mr. Bugman,
This bug alighted on my plate this evening at dinner on the patio. Curious to know what it is.

Mayfly

Dear Emily,
This is a Mayfly, and we are confident it is in the genus
Callibaetis which we discovered on Wayne’s Word and we verified on BugGuide that it might be Callibaetis pallidus.  Another species in the genus pictured on BugGuide that looks quite similar is Callibaetis californicus.  Mayfly nymphs are aquatic, so there must be some nearby body of water that will allow the nymphs to develop.  Winged adults are feeble fliers that cannot travel great distances.
