Habitat & Geographic Range

American Bald Eagle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

cockchafer maybeetle

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, Sweden, and Switzerland.

American Bald Eagle

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

cockchafer maybeetle

The cockchafer or maybeetle (Melolontha melolontha) is a large scarab beetle in the family Scarabaeidae, native to temperate Europe from the British Isles east across the continent to western Russia and the Caucasus. Adults, measuring 25–30 millimetres in length, are robust insects with chestnut-brown elytra, a distinctive fan-shaped antennal club, and a pointed abdomen tip. Emergent flights typically occur in May — hence the alternate name maybug — when adults aggregate in trees to feed on leaves and mate in sometimes spectacular swarms. The life cycle is three to five years long: eggs are laid in soil, and the pale C-shaped larvae spend multiple years underground feeding on plant roots, particularly those of grasses and agricultural crops, before pupating and completing metamorphosis. This subterranean larval phase can cause significant damage to pastures, cereals, and turf. Historically abundant across Europe, populations of M. melolontha declined dramatically during the twentieth century due to widespread use of soil insecticides in agriculture. Following restrictions on persistent organochlorine pesticides, populations have partially recovered in several countries, including Germany, Switzerland, and France, sometimes reaching pest status again. The species is classified as Least Concern by the IUCN but remains a subject of integrated pest management research. Natural enemies include rooks, badgers, moles, and various insect parasitoids that attack larvae in soil.
