The Rare Five-Spot Ladybird Coccinella quinquepunctata (Coleoptera: Coccinellidae) Surviving in an Unstable Habitat

Frontiers in Conservation Science, 2022
Coccinella quinquepunctata (the five-spot ladybird), was considered extinct in the UK until 1987. Since this time the species is abundant, however, only in very specific habitat in Wales and Scotland.

Heating up parasitoid–host interactions: High temperature increased mortality of late‐instar braconid larvae and reduced ladybird recovery rate

Functional Ecology, Volume 40, Issue 4, Page 773-785, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract With ongoing climate change, temperature‐dependent outcomes of host–parasitoid interactions can affect ecosystem functioning and key ecosystem services such as biological control. However, most studies addressing the impacts of temperature on host–parasitoid systems are

Artificial infection of three ladybird species by the ectoparasitic fungus Hesperomyces harmoniae

Biological Control
The invasive harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae) threatens biodiversity by displacing native ladybird species and disrupting ecosystems.

Sex‐Specific doublesex Regulation Targeting the Color‐Patterning Gene h Underlies the Evolution of Wing Sexual Dimorphism in the Harlequin Ladybug Harmonia axyridis

Evolution &Development, Volume 28, Issue 1, March 2026.
doublesex regulates sexual dimorphism in elytral color patterns of Harmonia axyridis by downregulating the color patterning gene h in males. This regulatory link diverged in derived color morphs, coinciding with the loss of sex‐specific elytral color patterns.

Using citizen science as a research prioritization tool to detect co‐occurrences of the invasive species Harmonia axyridis

Insect Conservation and Diversity, Volume 19, Issue 2, Page 452-459, March 2026.
We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

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.

Effects of temperature and humidity on the presence and prevalence of a common fungal parasite on an invasive ladybird

Ecological Entomology, Volume 51, Issue 1, Page 86-97, February 2026.
We investigated how temperature and relative humidity influence the parasitic fungus Hesperomyces harmoniae on the invasive ladybird Harmonia axyridis under controlled laboratory conditions. Abiotic factors significantly affect parasitism: High relative humidity increased parasite prevalence, development rate, and load, while both low and high ...

Pisana polonica (Harmonia axyridis [Pallas], Coleoptera, Coccinellidae) - invazivna koristna vrsta

Acta Agriculturae Slovenica, 2012
V začetku novembra 2011 smo v okolici Ljubljane na zidovih posameznih stanovanjskih hiš opazili množičen pojav polonic. Nekaj primerkov smo izlovili, da bi določili vrsto.

Contrasted effects of human pressure on biodiversity in the UK: a multi‐taxonomic assessment using airborne environmental DNA

Ecography, Volume 2025, Issue 12, December 2025.
Human activities have significantly modified habitats, resulting in a global biodiversity crisis. In this study, we leveraged the first national‐scale biodiversity survey based on airborne environmental DNA, comparing the effects of three human pressure indices increasing in complexity and scope – a binary urban–rural index, an index integrating land ...
