Huaynaputina is a volcano in a volcanic plateau in southern Peru. Lying in the Central Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca plate under the continental South American plate. Huaynaputina is a large volcanic crater, lacking an identifiable mountain profile, with an outer stratovolcano and three younger volcanic vents within an amphitheatre-shaped structure that is either a former caldera or a remnant of glacial erosion. The volcano has erupted dacitic magma. In the Holocene, Huaynaputina has erupted several times, including on 19 February 1600 – the largest eruption ever recorded in South America. Witnessed by people in the city of Arequipa, it killed at least 1,000 people in the region, wiped out vegetation, buried the surrounding area with 2 metres (7 feet) of volcanic rock and damaged infrastructure and economic resources. The eruption caused a volcanic winter and may have played a role in the onset of the Little Ice Age. Floods, famines, and social upheavals resulted, including a probable link with the Russian Time of Troubles. (Full article...)

The oak eggar (Lasiocampa quercus) is a common moth in the family Lasiocampidae found in Europe and northern and western parts of Asia. The larvae feed on a wide variety of plant species, low down, including blackthorn, hawthorn, viburnum, dogwood, ivy and ling, but are not known to feed on oak. They can be infected by baculoviruses, which change their behaviour and cause them to climb out of the protection of low scrub and leave them open to predation, facilitating the spread of infection. Oak eggar larvae eventually pupate on the ground inside a silken cocoon, the exterior of which is hard and yellowish, and resembles an acorn, from which the common name "oak eggar" is derived. This oak eggar larva in the form of a fourth-instar caterpillar, with a body length of 53 millimetres (2.1 inches), was photographed on a branch in Keila, Estonia. The photograph was focus-stacked from 59 separate images. Photograph credit: Ivar Leidus
