Clover case-bearer

The clover case-bearer (Coleophora alcyonipennella) is a small moth in the family Coleophoridae, order Lepidoptera. True to the family name, the larvae construct portable cases from plant material or silk and plant fragments, dragging these cases as they feed, a unique behavioral adaptation that provides both protection and concealment. C. alcyonipennella is a specialist herbivore of leguminous plants, with larvae feeding primarily on clover species (Trifolium) and related plants in the family Fabaceae. Larval feeding can cause characteristic window-feeding damage visible on leaves, and heavily infested plants may show significant defoliation. The adults are narrow-winged moths with wing markings typical of the coleophorid family, and like most coleophorids, they are small and inconspicuous. The species is distributed across temperate Europe, with documented occurrences in Belgium, Denmark, Norway, and Sweden, inhabiting diverse grassland, meadow, and agricultural habitats where its host plants are found. It is associated with both natural and semi-natural grasslands as well as agricultural fields and roadside verges. C. alcyonipennella is classified as Least Concern on the IUCN Red List, with populations considered stable across its European range. The species has one generation per year in most of its range, with larvae overwintering in their portable cases before completing development in spring on expanding host plant foliage. Adults fly in summer.

Common Seahorse

The common seahorse is found in tropical and temperate waters. Males carry and deliver the babies.
