Biologist Grace Herzel and colleagues conducted a study of how butterfly color and weather conditions relate to butterfly behavior, which wouldn't have been possible without data gathered by students and other amateur science enthusiasts in the community. Considering over three years' worth of data, the researchers found that white butterflies were observed on green flowers more often than any other butterflies were, and that butterflies were observed to feed more often on cloudy days than on other days.
According to the text, which factors seemed to be linked to the behavior of butterflies in Grace Herzel and colleagues' study?
Weather conditions but not butterfly color
A
Butterfly color but not weather conditions
B
Neither butterfly color nor weather conditions
C
Both butterfly color and weather conditions
D
