Abstract

Nagari et al. report that bumble bee workers reduce sleep in the presence of larvae that need to be fed or pupae that do not. Emptied cocoons induce a similar but transient effect, suggesting that pupal substances mediate the brood effect on sleep. This is the first evidence that animals give up sleep to care for offspring that are not their own.
