COVER PHOTO: Monarch (Danaus plexippus) larvae are voracious herbivores in their final stage of larval development. In a series of laboratory experiments, we tested for direct, indirect, and combined effects of warming on a critical part of the monarch–milkweed interaction. Even in a relatively simple, short-term experiment, we found variability among these different effects of warming that highlights challenges for predicting the broader effects of climate warming on ecological communities.
