Molecular evolution of dietary shifts in ladybird beetles (Coleoptera: Coccinellidae): from fungivory to carnivory and herbivory [PDF]
BMC BiologyBackground Dietary shifts are major evolutionary steps that shape ecological niches and biodiversity. The beetle family Coccinellidae, commonly known as ladybirds, first transitioned from a fungivorous to an insectivorous and subsequently a plant diet ...

Urbanization Negatively Affects the Species Composition of Native Ladybirds in Central Europe
Frontiers in Conservation Science, 2021 We evaluated the differences in frequency (percentage of sampling sessions where the species was recorded) and abundance (mean number of individuals per 100 sweeps) of native species of ladybirds (Coleoptera: Coccinellidae) in the center of Prague ...

Geographic variation in evolutionary rescue under climate change in a crop pest–predator system [PDF]
Evolutionary ApplicationsSpecies distribution models (SDMs) are often built upon the “niche conservatism” assumption, such that they ignore the possibility of “evolutionary rescue” and may underestimate species' future range limits under climate change.

Exotic predators are not better biocontrol agents: the harlequin ladybird is not the most voracious in Mexico [PDF]
PeerJ, 2021 The use of exotic species for pest biocontrol has been a common pathway for introduction and dispersal of invasive species that may have undesired outcomes.

Warm Mesoclimate Advances the Seasonal Dynamics of Harmonia axyridis in Urban Habitats
Frontiers in Ecology and Evolution, 2021 In 2016–2019, seasonal changes in the abundance of the harlequin ladybird Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) were established in the city center of Prague, Central Europe, and in its outskirts.

Overwintering of ladybirds (Coleoptera: Coccinellidae) on Scots pine in Central Europe
European Journal of Entomology, 2018 We surveyed ladybirds (Coleoptera: Coccinellidae) in 10 stands of Scots pine (Pinus sylvestris), all monoculture stands 5-100 years old, in western Slovakia, Central Europe, over two successive periods, October 2013 - March 2014 and October 2014 - March ...
