Some males sit on the pupae of female butterflies for up to 10 days before they hatch, to get first dibs at mating with them – but how do they know it's a female in there?

Scientists have observed ants feasting on a nutrient-rich substance released by other ants. Pupae, ants in the last stage of ant metamorphosis before they become adults, secrete the liquid. Both ...

The study, published in Nature, reveals that pupae secrete a never-before observed fluid that adults and larvae immediately drink. The health of the entire colony appears to hinge on the prompt ...

The pupae depend on the adults and larvae to remove the liquid so that they don’t get an infection, and the larvae rely on it to aid their growth, says Kronauer.

Moulting fluid from ant pupae is a food source that aids colony success. Parental-care behaviours include mammalian lactation to provide milk for offspring.
