The Science: 
The parallel spectrums in this artwork represent the change in color experienced by both spruce trees 
and beetles during an infestation. The upper spectrum illustrates the color of tree needles as they fade from dark green to grey, while the lower spectrum demonstrates the beetle’s color as it matures from larvae to adult form. These shifts in color happen simultaneously as nutrients are channeled from the tree to the beetles.
