白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

Common Fruit-tree Pigmy

<em>Stigmella oxyacanthella</em>, commonly known as the common fruit-tree pigmy, is a small moth in the family Nepticulidae. This species has been documented in Belgium, Denmark, Norway, and Sweden, and its range is understood to extend more broadly across parts of Europe. Nepticulidae moths are among the smallest Lepidoptera, and species in this family are typically leaf miners, with larvae feeding within the leaf tissue of host plants. <em>Stigmella oxyacanthella</em> is associated with woody plants in the rose family (Rosaceae), with its common name reflecting an association with fruit trees and hawthorn. The species is assessed as Least Concern, consistent with its distribution across multiple northern European countries. As a leaf-mining species, it contributes to insect diversity within deciduous woodland and orchard habitats. Biological traits of this species remain poorly documented in the scientific literature. The adults are characteristically tiny, with narrow wings and long antennae, and are most readily identified through the distinctive leaf mines produced by their larvae rather than by direct observation of the adult moths.
