After harsh adult dusty cochineal bugs that Bowers purchases from Mexico or Peru, students flow a dejected insects into prohibited water, that turns red, pinkish and orange. The students drop fabric into a colored H2O to make tie-dye scarves.
Students taking Bowers’ class study how insects correlate with their sourroundings and other organisms, examining insect morphology, physiology and growth to build a context for bargain insect ecology, function and evolution.
