- the tree trunk was brown in color, the brown colored moths increased in frequency because they are harder to see due to camouflage
- The light moths will soon die off because they can't camouflage well in the habit and the brown moths are increasing more
- Over the five year span, the percent of brown moths increase while the percentage of light moths decreases.
