Alle origini di un mimetismo batesiano: Evolvability dei patterns cromatici di Vespidae e Syrphidae [PDF]

, 2022
Lavoro sull'ipotesi di un pattern cromatico comune tra Vespidae e Syrphidae. La colorazione gialla e nera di questi insetti è una colorazione aposematica, di avvertimento.

Fishing for flies: testing the efficacy of “stink stations” for promoting blow flies as pollinators in mango orchards

Journal of Pollination Ecology, 2023
Pollinator communities are composed of diverse groups of insects, with radically different life histories and resource needs. Blow flies are known to visit a variety of economically important crop plants.

Evaluating the effects of observation period, floral density, and weather conditions on the consistency and accuracy of timed pollinator counts

Journal of Pollination Ecology, 2022
Insect pollinators are experiencing substantial declines as a result of habitat loss, agricultural intensification, invasive pests, and climate change. To investigate factors causing pollinator declines, evaluate the success of conservation measures, and

Genetic structure and phenotypic diversity of two northern populations of Cheilosia aff. longula (Diptera: Syrphidae) has implications for evolution and conservation

European Journal of Entomology, 2010
The genetic structure and phenotypic diversity of two populations of Cheilosia aff. longula (Diptera: Syrphidae) in Lapland, Finland, were examined using DNA sequencing, protein electrophoresis, and geometric morphometrics.

Detailed morphological descriptions of the immature stages of the ant parasite Microdon mutabilis (Diptera: Syrphidae: Microdontinae) and a discussion of its functional morphology, behaviour and host specificity

European Journal of Entomology, 2017
The myrmecophilous immature stages of hover flies of the genus Microdon Meigen, 1803 (Diptera, Syrphidae) are still poorly known and only about 15 species were previously incompletely described and/or illustrated using light microscopy based on ...

Syrphid aphidophagous predators in a food-web context

European Journal of Entomology, 2005
The main influences on the specificity of hoverfly larvae (Diptera: Syrphidae) to particular aphids are outlined. There are four main ones: aphid species, host plant, parasitoid impact and the presence of ants.
