Flower Associations of Mimetic Syrphidae (Diptera) in Northern Michigan [PDF]
, 2017 Collections of specialized (high fidelity) mimetic Syrphidae in northern Michigan revealed 19 species associated with 18 flowering plants. Almost 97% of these syrphids were taken on seven plant species or species groups, all with conspicuous white or ...

Evidence for hilltopping in bumblebees? [PDF]
Ecological Entomology, 2011 1. Male bumblebees are known to exhibit a range of mate‐location behaviours, including perching on prominent objects and darting at passing queens, patrolling of scent‐marked flight routes, and waiting outside nest entrances for virgin queens to emerge. Here we provide evidence for a fourth strategy, known as hilltopping. This behaviour is widely known

Super-entropy bumblebee AdS black holes
Physics Letters BMotivated by the effect of the bumblebee field on thermodynamic instability in (non)extended phase space, we study the thermodynamic instability for the bumblebee AdS black holes. For this purpose, first, we evaluate the effect of the bumblebee field (or

Distribution of bumblebees across Europe [PDF]
One Ecosystem, 2018 Insect pollinators are a key component of biodiversity; they also play a major role in the reproduction of many species of wild plants and crops. It is widely acknowledged that insect pollinators are threatened by many environmental pressures, mostly of anthropogenic nature. Their decline is a global phenomenon.

American Journal of Botany, EarlyView.Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

A Local Replacement of \u3ci\u3eBombus Ternarius\u3c/i\u3e by \u3ci\u3eBombus Terricola\u3c/i\u3e in Northern Wisconsin (Hymenoptera: Apidae) [PDF]
, 2017 During the last few years, the bumblebee Bombus ternarius Say has markedly decreased in numbers in Vilas County in northern Wisconsin while Bombus terricola Kirby has increased. The great ecological similarity of these species suggests that interspecific
