Common Purple & Gold

The Common Purple and Gold, <em>Pyrausta purpuralis</em>, is a small moth in the family Crambidae, subfamily Pyraustinae, found across northern and western Europe including Belgium, Denmark, Norway, and Sweden. It is a distinctively patterned species with rich purple-crimson forewings marked by bright golden-yellow spots and patches, making it one of the more visually striking micro-moths of the European fauna. The species typically inhabits calcareous grasslands, chalk downs, coastal cliffs, and heathlands where its larval host plants, particularly species of wild thyme (<em>Thymus</em>) and marjoram (<em>Origanum</em>), are abundant. The caterpillars typically feed on the leaves and stems of these aromatic herbs in sheltered, sun-exposed sites. Adults fly in one or two generations per year, typically from late spring through summer, and are diurnal, often seen nectaring on flowers in warm sunshine. <em>Pyrausta purpuralis</em> is assessed as Least Concern on the IUCN Red List given its distribution across suitable habitats in Europe. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
