Floral specialization for beetle pollination and its implications for pollen dispersal in an African orchid

American Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Premise Pollination by beetles is relatively rare in orchids, and this has been attributed to the clumsy behavior of beetles being unsuitable for the precise pollen transfer mechanisms that characterize the orchid family. We investigated floral specialization for beetle pollination in the rare fire‐dependent South African orchid Disa elegans ...

Systematic Continental Scale Monitoring by Weather Surveillance Radar Shows Fewer Insects Above Warming Landscapes in the United States

Global Change Biology, Volume 31, Issue 11, November 2025.
Systematic remote sensed monitoring of insect density in the air shows fewer insects above warming landscapes in the United States. We estimate insect density at continental scales for the first time by leveraging the nationwide network of weather radars.

Biogeography and Social Family Structure Contribute to Cryptic Genomic Divergence in the Only Obligate Eusocial Beetle Species, Austroplatypus incompertus (Curculionidae: Platypodinae)

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Eusociality in insects has arisen multiple times independently in Hymenoptera (bees, wasps and ants), Blattodea (termites) and Coleoptera (beetles). In Hymenoptera and Blattodea, the evolution of eusociality led to species proliferation. In the hyperdiverse Coleoptera, obligate eusociality evolved only once, in the ancient Australian ambrosia ...
