Blue Featherleg

ヨーロッパから西アジアにかけての静水および緩流の淡水生息地に生息する中型のイトトンボで、ブルーフェザーレッグ（Platycnemis pennipes）は求愛ディスプレイ中に振り動かすオスの後脚の脛骨の羽毛状の縁取りから命名されました。オスは薄い青色、メスはオリーブグリーン色を示します。抽水植物に止まり、河川環境の水質の良い指標種です。水質汚染と農業の集約化により、一部の地域で個体数が減少しています。

Common Roller

<em>Ancylis badiana</em>, the common roller, is a small moth in the family Tortricidae, order Lepidoptera. It is distributed across northwestern Europe, with documented records from Belgium, Denmark, Norway, and Sweden, typically inhabiting woodland margins, hedgerows, scrubland, and areas where its larval host plants are abundant. The species is assessed as Least Concern on the IUCN Red List. Tortricid moths in the genus Ancylis are commonly known as "rollers" or "leafrollers" because their larvae typically roll or fold leaves of host plants to create sheltered feeding structures. <em>Ancylis badiana</em> larvae feed on the foliage of various herbaceous plants, particularly species in the pea family (Fabaceae). Adults are small moths with intricately patterned wings that provide camouflage against bark and plant material. Adult moths are primarily nocturnal and are attracted to light, while larvae are cryptic within their leaf shelters. Biological traits such as lifespan, body measurements, and detailed diet host range remain poorly documented beyond general family-level characteristics. The species typically completes one to two generations per year in temperate European climates, overwintering as pupae. It is considered a minor component of invertebrate biodiversity in European lowland habitats.
