Beyond Deception: What Else Do Flower Wasps (Hymenoptera: Thynnidae: Thynninae) Do in Flowers Worldwide?

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Wasps, although less recognised as good pollinators, also feed on nectar and pollinate flowers. Specialised pollination systems, such as orchids that mimic the pheromones of female wasps to attract males, are complex and specific. This interaction occurs with some Thyninnae wasps that also visit flowers to obtain nectar and perform other ...

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

open access: yesMolecular Ecology, EarlyView.
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 ...
