Boxplot of minimum interspecific and maximum intraspecific genetic distances per sequence from all COI and ITS2 sequences of black flies.

The median is indicated by the line inside the box. The lower and upper hinges correspond to the first and third quartiles (the 25th and 75th percentiles). The upper whisker extends from the hinge to the largest value no farther than 1.5 * IQR from the hinge (where IQR is the inter-quartile range, or distance between the first and third quartiles). The lower whisker extends from the hinge to the smallest value, at most 1.5 * IQR of the hinge. Data beyond the end of the whiskers are outlying points and are plotted individually.
