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.

Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.
