pigargo-americano

A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.

Cock's-head Bell

The cock's head bell moth (Zeiraphera isertana) is a small tortrix moth in the family Tortricidae, occurring across deciduous and mixed woodland habitats in northern and central Europe, including Belgium, Denmark, Norway, and Sweden, as well as Britain and much of temperate continental Europe. Adults have a wingspan of approximately 16–22 millimetres and display intricate grey, brown, and white patterning on the forewings that provides effective cryptic camouflage against tree bark and lichens. The species flies in a single generation from July to September, and adults are nocturnal, coming to light. Larvae feed on the foliage of a range of deciduous trees, with oak (Quercus), hazel (Corylus), and related broadleaf species among the recorded host plants; larvae spin and bind leaves together as feeding shelters in a manner typical of many tortricid moths. Pupation occurs in leaf litter or bark crevices. Zeiraphera isertana is classified as Least Concern by the IUCN, reflecting its wide distribution and association with a broad range of common host tree species in well-established broadleaf woodland across its European range. The species belongs to a large genus that includes some economically important pests of conifers and orchards, though Z. isertana itself is not considered a significant pest. It is regularly recorded in standard moth surveys across Scandinavia and central Europe.
