This article is so bizarre, not because I doubt its scientific authenticity, but just because of the material it covers. Really, it’s just caterpillars. I think the title to the article would make a good title for a pseudo-autobiographical novel: Caterpillars are more likely to vomit alone. I will begin an outline immediately.
Extended quote:
This new study shows that there is a social side to defensive vomiting. The researchers found that whether a caterpillar is willing to regurgitate — and to what extent — depends on the size of its social group.
