“…In this context, open‐canopy ponds with associated sun‐exposed flowering herb‐rich margins may provide important pollinator habitats, especially where restoration and management activities do not remove all woody vegetation, thus leaving a wide variety of microhabitats (Sayer et al ., 2013) and accommodating a variety of trees, shrubs, herbaceous perennials and annual flowering plants. Additionally, wood debris and other detrital plant matter left within open‐canopy pond margins in conjunction with marginal plant vegetation can provide suitable nesting habitat for many adult hymenopteran species (Roulston & Goodell, 2010; Westerfelt et al ., 2015), as well as larval resources for saprophytic hoverfly species (Hartley, 1963; Rotheray & Lyszkowski, 2015; Rotheray, 2019), thus further contributing to the diverse micro‐habitat conditions characteristic for these ponds.…”

Declines in pollinating invertebrates across intensively cultivated landscapes linked to reductions in flower‐rich habitats constitute a key threat to biodiversity conservation and the provision of ecosystem services. Over recent decades, many ponds in agricultural landscapes have become overgrown with woody vegetation, resulting in heavily shaded, flower‐poor pond basins and margins. Restoration of farmland ponds through removal of sediment and encroaching woody vegetation (canopy management) from pond margins greatly enhances freshwater biodiversity. Nevertheless, the consequences of pond management for pond‐margin plants and pollinating insects remain poorly understood. Here, we studied these effects for ponds in Norfolk, eastern England. We compared richness, abundance and composition of pollinating insects (hymenopterans and syrphids) and insect‐pollinated plant communities between open‐canopy pond systems subjected to either (i) long‐term regular management of woody vegetation or (ii) recent restoration by woody vegetation and sediment removal with those communities at (iii) ponds dominated by woody vegetation. Canopy management increased the richness and abundance of pollinators and insect‐pollinated plants. Pollinator richness and abundance was best explained by improvements in flower resources at open‐canopy ponds. Management most strongly influenced hymenopteran communities. Ponds represent important semi‐natural habitats for insect‐pollinated plant and pollinator communities in farmland. To enhance food resources, diversity and abundance of diurnal pollinators, conservation management at ponds should aim for mosaics of ponds at different successional stages with a high proportion of early successional open‐canopy ponds. Agricultural ponds are emerging as important habitats not only for aquatic biodiversity, but also for terrestrial species, thus warranting their prioritisation in future agri‐environment schemes.

“…These microorganisms can enter the BSF’s body cavity (hemocoel) either by being consumed and penetrating the insect’s gut or through the insect’s cuticle. Therefore, the BSF can harbor a vast variety of microorganisms, some providing nourishment while others are pathogenic or pass through the alimentary tract unaffected ( Nayduch and Burrus 2017 , Rotheray 2019 ). In addition, these environments are highly changeable in their biotic and abiotic condition as the decay heads towards assimilation ( Ceustermans et al 2010 ).…”

Detritivorous insects that flourish in decaying environments encounter microorganisms throughout their life cycle. However, it is not clear whether the microbial composition of the decaying environment affects the microbial composition of the insect gut, or whether the opposite is true, with the microorganisms that are adapted to the insect’s digestive system being dispersed by the insects to new habitats, thereby becoming more and more common in the environment. To test these questions the fungal composition of the black soldier fly (BSF) (Stratiomyidae; Hermetia illucens Linnaeus) larval gut and its surrounding decaying environment (household compost bins) were analyzed using amplicon sequencing. Constancy in the dominance of the genus Candida (Debaryomycetaceae) in most of the environments and larval guts was found. This finding may suggest a ‘core’ structure to the fungal community of the BSF. In locations where nutrient composition of the environment had higher fiber content, the Candida was not dominant and the most common fungi were the genus Gibberella (Nectriaceae) and the family Dipodascaceae. The later was dominant also in the larval gut and the former was replaced with Meyerozyma (Debaryomycetaceae), which may suggest a selection process by the insect’s gut. Little is known about the ecological interactions of insects with eukaryotic microorganisms, such as yeast-like fungi. As their metabolic complexity and ability is intense, they have the potential to dramatically affect the physiological condition of the insect.
