Flooded semi-natural grasslands are endangered ecosystems throughout Europe. In Italy, amongst flooded meadows, one special type called "" is strongly threatened. It is a stable flooded grassland used to produce green forage even during winter months due to the thermal properties of water coming from springs and fountains that prevent the soil from freezing. To date, some research has been carried out to investigate the role of the for ornithological and herpetological communities. However, no comprehensive data on invertebrates inhabiting this particular biotope available. The aim of this study was to characterise the terrestrial entomological community of these typical winter-flooded meadows in northern Italy and, in particular, in six fields located in the Ticino Valley Regional Park. We collected data on species richness and diversity of Carabidae, Staphylinidae, Araneae, Lepidoptera and Orthoptera inhabiting during the summers of 2014 and 2015 and data on overwintering Coleoptera during the winter of 2014-2015. Amongst the collected species, we identified those highly linked to this habitat.
We found a total of 47 ground beetle species, 35 rove beetle species, 29 spider species, one Lucanidae, 16 butterfly species and 24 grasshopper and cricket species. Most of the species were collected during the summers of 2014 and 2015, while some others were also, or exclusively, overwintering (17 ground beetles, four rove beetles and one Lucanidae) and were collected during the winter of 2014-2015. fields hosted specialised species and species typical of hygrophilous habitats, amongst which are included the butterfly , the ground beetle and the grasshopper . This study represents the first contribution to the knowledge of terrestrial arthropod communities associated with this particular type of winter-irrigated meadow in Europe and confirms the importance of this biotope for invertebrate conservation in agricultural landscapes.
水淹半天然草地是整个欧洲濒临灭绝的生态系统。在意大利，在水淹草甸中，一种名为“ ”的特殊类型受到严重威胁。它是一种稳定的水淹草地，由于来自泉水和喷泉的水具有保暖特性，可防止土壤结冰，即使在冬季也能用于生产绿色饲料。迄今为止，已经开展了一些研究来调查“ ”对鸟类和爬行类群落的作用。然而，尚无关于栖息在这个特定生物群落中的无脊椎动物的全面数据。本研究的目的是描述意大利北部这些典型冬季水淹草甸的陆地昆虫群落特征，特别是位于提契诺河谷地区公园的六个“ ”田地中的昆虫群落特征。我们收集了2014年和2015年夏季栖息在“ ”中的步甲科、隐翅虫科、蜘蛛目、鳞翅目和直翅目的物种丰富度和多样性数据，以及2014 - 2015年冬季越冬鞘翅目的数据。在收集到的物种中，我们确定了那些与该栖息地高度相关的物种。
我们总共发现了47种步甲、35种隐翅虫、29种蜘蛛、1种锹甲科昆虫、16种蝴蝶以及24种草蜢和蟋蟀。大多数物种是在2014年和2015年夏季收集到的，而其他一些物种也是或仅在冬季越冬（17种步甲、4种隐翅虫和1种锹甲科昆虫），并于2014 - 2015年冬季收集到。“ ”田地中有一些特化物种和典型的喜湿生境物种，其中包括蝴蝶“ ”、步甲“ ”和草蜢“ ”。本研究是对欧洲这种特定类型冬季灌溉草甸相关陆地节肢动物群落知识的首次贡献，并证实了这个生物群落对于农业景观中无脊椎动物保护的重要性
