That is a really high black one. Wow. I saw the two records of your finds in nevada county, and found one record of one more online. I'm sure a lot more have been found, just not by anybody putting the photos online. It looks like both of yours were over 4000 ft. Mine was at 2600, the other was at 2500. If it took six years to find two zonata, I better get up on it. I might end up going a couple of years without finding another. I have read stories of people finding a dozen in one day of searching, but usually farther south like Kern County. Is that just because more people search for them there?
