Caption: Rice University undergraduate researcher Zhengji "Jim" Sheng prepares to place samples of lettuce and caterpillars in a chamber with controlled lighting. The notation DL refers to the dark-light circadian rhythm of the caterpillar. When the circadian clock of the lettuce matches that of the caterpillar, the leaves are less likely to be eaten.
