Found a cool[*] bee fly (Hemipenthes jaennickeana?). Check out subtle styling in the wavy patterns on those wings! #photography #flies #insects 
Taken near Folsom Lake, California

[*] all bee flies are cool.

 @37fbbf36 Nice! I can see the crossvein in the Rs near the wingtip, so I think you’re right about jaennickeana.
