Beetle Pollination in the Holoparasitic Lophophytum pyramidale (Balanophoraceae): A New Case of Brood‐Pollination Mutualism?

Journal of Applied Entomology, EarlyView.
ABSTRACT Beetle pollination is considered an ancestral trait in angiosperms, retained in a few specialised families engaging in longstanding interactions with ancient groups of beetles. While beetles represent some of the earliest angiosperm pollinators, there is also increasing evidence that some beetle‐pollinated plants represent a derived condition.

Perceptions of adaptation, resilience and climate knowledge in the Pacific: The cases of Samoa, Fiji and Vanuatu [PDF]

International Journal of Climate Change Strategies and Management, 2018
Purpose – While the South Pacific is often cited as highly vulnerable to the impacts of climate change, there is comparatively little known about how different groups perceive climate change.

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

Molecular 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 ...

24 million years of pollination interaction between European linden flowers and bumble bees

New Phytologist, EarlyView.
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.

The draft genome sequence of the Japanese honey bee, Apis cerana japonica (Hymenoptera: Apidae)

European Journal of Entomology, 2018
Honey bees are not only important for honey production but also as pollinators of wild and cultivated plants. The Eastern honeybee (Apis cerana) is more resistant to several pathogens than the Western honeybee (Apis mellifera), and the genomes of two ...

Ecological factors underlying the spatiotemporal dynamics in a key forest beetle pollinator Facteurs écologiques à la base de la dynamique spatio‐temporelle d'un important coléoptère forestier pollinisateur

Agricultural and Forest Entomology, Volume 27, Issue 4, Page 590-599, November 2025.
Eusphalerum, an understudied beetle pollinator in North America, comprises over 50% of beetle specimens collected using flight‐intercept traps in forests across New Brunswick, Canada. In a study investigating its phenology, congeneric aggregation and population dynamics, we demonstrated that Eusphalerum exhibits unique phenology distinct from other ...

Floral strips increase the abundance and spillover of beneficial insects in rotational crop fields

Agricultural and Forest Entomology, Volume 27, Issue 4, Page 653-670, November 2025.
Abstract Insects provide many ecological functions that support agricultural production, but beneficial insect populations are often lower in areas of intensive agriculture. Agronomic practices that support beneficial insect populations are important for sustainable crop production.

Male territorial behaviour of the endemic large carpenter bee, Xylocopa (Koptortosoma) ogasawarensis (Hymenoptera: Apidae), on the oceanic Ogasawara Islands

European Journal of Entomology, 2008
The endemic large carpenter bee, Xylocopa (Koptortosoma) ogasawarensis Matsumura (Hymenoptera: Apidae), on the oceanic Ogasawara (Bonin) Islands, located in the northwestern Pacific Ocean, approximately 1000 km south of the Japanese mainland, is a ...

Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations

Biotropica, Volume 57, Issue 6, November 2025.
In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.
