This document discusses the life cycle of the Large Blue butterfly species Maculinea, which has an unusual relationship with ants. Only 1% of insect species are aphytoghagous, meaning they eat ants, including Maculinea caterpillars that spend winters underground in ant colonies eating the ants. The document raises questions about how the caterpillars are found by the ants and how they remain undetected while living in the ant colony for long periods.
