Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Ant-Pollinator Conflict Results in Pollinator Deterrence but no Nectar Trade-Offs
Direct and indirect negative interactions between ant guards and pollinators on ant-plants are expected for two reasons. First, aggressive ants may deter pollinators directly.

The predatory behavior of ants: an impressive panoply of morphological adaptations
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Ants contribute to raspberry pollination in protected cropping systems
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Ecophysiological aspects of nectar reabsorption
A number of approaches, both direct and indirect, have shown that nectar is reabsorbed by numerous plant species, irrespective of the age or sex of the flower.

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

Towards elucidating the differential regulation of floral and extrafloral nectar secretion [PDF]
Nectar is a rich source of sugars that serves the attraction of pollinators (floral nectar) or predatory arthropods (extrafloral nectar). We just begin to understand the similarities and differences that underlie the secretory control of these two important types of plant secretions.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial
