De första svenska fynden av parköronvivel Otiorhynchus crataegi Germar, 1824 (Coleoptera: Curculionidae)

• crataegi Germar, 1824. The first specimen was found in the city of Malmö in the southernmost province of Sweden in the beginning of October 2020, where one individual had taken shelter from a heavy morning rain on a house wall, together with several other beetle species. The species was subsequently sought after during late autumn and winter by sifting litter beneath putative host plants, but it could not be relocated until May 2021 when a large, but local, population was found in a scarlet firethorn (Pyracantha coccinea) hedge some hundred metres from the original location. The species has since then been observed in the same hedge on numerous occasions, suggesting that O. crataegi might be established in southernmost Sweden. Its sudden appearance in Sweden seems to be the result of an unintentional introduction with ornamental hedging plants from continental Europe rather than of a natural range expansion from nearby Denmark.
