EXAM 1 SPECIES IDENTIFICATION KEY (94 POINTS)
Nota Bena (Note Well): Since this exam had a total of 94 points, every one was awarded 6 extra credit points to bring the total point value of this exam up to 100 points.  These extra points are recorded in the Sting Point column of the Niihka gradebook, in addition to 3 points for the trauma of the bees; and if you actually got stung, 3 additional points for the first sting + plus 2 points per stings above that, as reported by you to me.
