The European spruce bark beetle (Ips typographus), is a species of bark beetle in the true weevil family, Curculionidae. It is found in Europe and Asia Minor and east to China, Japan, North Korea and South Korea. Bark beetles are so named because they reproduce in the inner bark, living and dead phloem tissues, of trees. Their preferred trees in which to reside include spruces, firs, pines and larches. The species has the ability to spread quickly over large areas and some scientists hypothesize that long-distance movements originating from the Iberian Peninsula may have contributed to its invasion of northern Norway spruce forests. This female European spruce bark beetle was photographed in Naninne in the province of Namur, Belgium.Photograph credit: Ivar Leidus
Two date formats are commonly used in Wikipedia articles: December 2, 2009 and 2 December 2009. These are referred to as alphanumeric dates. The first is used in articles with a connection to the United States, and the second in articles relating to most Commonwealth countries (although no preference is expressed for Canada). In articles with no particular national affiliation, to prevent needless edit warring, the established date format should not be changed. However any given article should use just one of the two formats consistently. Dates that are all numeric are highly discouraged to avoid confusion, however if used must be in the YYYY-MM-DD format and never in YYYY-DD-MM format.
