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.

Delfín tonina

La especie de delfín más estudiada y reconocida, los delfines mulares habitan océanos cálidos y templados de todo el mundo, desde las aguas costeras poco profundas hasta el mar abierto. Altamente inteligentes con grandes cerebros en relación con el tamaño corporal, demuestran autoreconocimiento, comunicación compleja y aprendizaje social. Viven en sociedades fluidas de fisión-fusión y cooperan para arrear peces. Una especie indicadora clave de la salud del ecosistema marino.
