FIGURE 4 in Repeatability and precision in proboscis length measurements for long proboscid flies

FIGURE 4. Extent of potential proboscis extension by species/species group (labrum length mm). Bold bar indicates median, upper and lower box bounds indicate 25th and 75th percentiles (=middle 50% of data). Error bars indicate the smaller of either 1) 1.5 x interquartile range (~ 2 standard deviations), or 2) maximum/minimum value; outliners are points beyond these error bars.
