Iberian harvester ant queens are cloning different species to produce hybrid workers

This new frontier in reproduction is referred to by the authors as "xenoparous," meaning the ant queens have a need to produce individuals of another species as an inherent part of their life cycle. The exact developmental mechanism of cross-species male cloning is still unknown, but the authors have some theories.

(Earlier: Why the UK’s butterflies are booming in 2025)

Why are we seeing so many butterflies in Ireland this year?

Another reason for the 2025 butterfly boom is the weather in Europe. Hot, dry weather creates drought, and butterflies capable of migration escape by altitudinal and geographical migration. By moving north, Clouded Yellow, Large White, Small White, Red Admiral and Painted Lady butterflies can find succulent foodplants for their caterpillars.

Birds found thriving in a very large commercial forest in Maine

North America has lost an estimated 3 billion birds since 1970—a nearly 30% drop across species—mostly due to habitat loss and degradation. So when a team of researchers repeated a bird population study they did 30 years earlier in a very large commercial forest landscape in Maine, they were stunned to find more birds than before.
