Studies on saproxylic species of Coleoptera have garnered significant attention due to the rarity of some of them. To investigate the distribution and biology of (Kraatz, 1880) (Scarabaeidae: Cetoniinae) in European Russia, we analyzed data from 16 regions collected between 2018 and 2024. This species has been reliably recorded in 26 regions. We describe the species' distribution area boundaries and discuss limiting factors that inhibit its spread to the north, south, and southeast of European Russia. The primary limiting factor is the lack of suitable biotopes. Within its distribution, prefers deciduous and mixed forests of various types. These habitats include both old-growth forest ecosystems and secondary forests that have regenerated following logging. The species also inhabits man-made forest ecosystems, such as field protection forest belts, old parks, and gardens. In forest ecosystems, tends to occupy the upper levels and is rarely found on the ground layer. Conversely, in open areas such as glades, the species is more commonly found at ground level. This distribution pattern is linked to the adults' feeding preferences, which include consuming sap on tree trunks in forests and feeding on flowering plants in open ecosystems. The seasonal activity of peaks from the third decade of June to the second decade of July. It is hypothesized that the perceived rarity of in research samples is due to the specific baiting methods used, with beer traps being the most effective. The status of the species is re-evaluated in light of new data, suggesting that is common rather than rare in European Russia.
由于鞘翅目腐木昆虫物种中的一些种类较为罕见，对它们的研究已受到广泛关注。为了调查欧洲俄罗斯地区（Kraatz，1880）（金龟科：花金龟亚科）的分布和生物学特性，我们分析了2018年至2024年期间从16个地区收集的数据。该物种已在26个地区被可靠记录。我们描述了该物种的分布区域边界，并讨论了抑制其向欧洲俄罗斯北部、南部和东南部扩散的限制因素。主要限制因素是缺乏合适的生物栖息地。在其分布范围内，该物种偏好各种类型的落叶林和混交林。这些栖息地包括原始森林生态系统以及伐木后再生的次生林。该物种还栖息于人造森林生态系统，如农田防护林带、古老公园和花园。在森林生态系统中，该物种倾向于占据上层，很少出现在地面层。相反，在开阔区域如林间空地，该物种更常见于地面。这种分布模式与成虫的取食偏好有关，成虫在森林中取食树干上的树液，在开阔生态系统中取食开花植物。该物种的季节性活动高峰期为6月的第三个十年至7月的第二个十年。据推测，研究样本中该物种被认为罕见是由于所使用的特定诱捕方法，其中啤酒诱捕器最为有效。根据新数据重新评估了该物种的地位，表明在欧洲俄罗斯该物种很常见而非罕见。
