This is the first time this phenomenon has been observed in a solitary and nocturnal lemur species.

A type of caterpillar which defends itself by regurgitating on its predators is less likely to do so when in groups than when alone, a new study by researchers from the University of Liverpool and the University of Bristol has found. Such reluctance is sufficient to cancel out the benefits of being in a group. The study, published in Ecology Letters, will help in the design of more sustainable methods for reducing crop losses caused by caterpillars and similar pests.
