Research on the fauna of beetles (Coleoptera) of the Canary Islands has a long tradition, which enables tracking changes in their species composition and arrival of new species. In this paper, we provide new faunistic data on the ladybird beetles (Coccinellidae) recorded on Gran Canaria, one of the central islands of the archipelago, and then analyze available information on the Gran Canarian ladybird fauna from geographical and historical points of view. The field survey resulted in recording 1402 ladybird individuals belonging to 30 species. Ten of these species were new to Gran Canaria and three of them, (Linnaeus), (Boheman), and Fürsch, had not previously been reported to be on any of the islands of the Canarian archipelago. (Hodgson) is synonymized with (Wollaston). Our survey and literature reports allowed us to recognize 42 species of Coccinellidae so far recorded on Gran Canaria. Seventeen of them (40%) belonged to the Canarian endemic and subendemic species, and 21 (50%) were newcomers and presumed newcomers. Colonization of Gran Canaria and other islands of the archipelago by ladybird species of various origins seems to be a frequent phenomenon that may pose a threat to the unique communities of the native Canarian species.
加那利群岛甲虫（鞘翅目）动物区系的研究有着悠久的传统，这使得追踪其物种组成的变化以及新物种的到来成为可能。在本文中，我们提供了关于大加那利岛（该群岛中部岛屿之一）上记录的瓢虫（瓢虫科）的新动物区系数据，然后从地理和历史角度分析了有关大加那利岛瓢虫动物区系的现有信息。实地调查记录了属于30个物种的1402只瓢虫个体。其中有10个物种是大加那利岛新发现的，其中3个物种，即（林奈）、（博赫曼）和菲尔施，此前未在加那利群岛的任何岛屿上被报道过。（霍奇森）与（沃拉斯顿）同义。我们的调查和文献报告使我们目前已识别出大加那利岛上记录的42种瓢虫科物种。其中17种（40%）属于加那利群岛特有和亚特有物种，21种（50%）是新出现的和推测为新出现的物种。各种来源的瓢虫物种对大加那利岛和该群岛其他岛屿的定殖似乎是一种常见现象，这可能对加那利群岛本土物种的独特群落构成威胁。
