Yellow Admiral

Fascinating facts about the Yellow Admiral

• The yellow admiral can cross the Tasman Sea by being carried on wind currents from Australia to New Zealand. Its reputation as a strong, fast flier underpins this ability, allowing it to remain airborne for long periods. Scientists believe this flight capability enables the butterfly to survive such wind-blown drift across the open ocean, linking the two landmasses.
• In New Zealand the yellow admiral's pupal stage is attacked by two wasp species that were introduced by humans. The self-introduced Echthromorpha intricatoria and the introduced Pteromalus puparum both parasitise the pupae, reducing survival rates during this vulnerable transformation. These interactions are recorded only in the New Zealand portion of its range.
• Some yellow admiral populations avoid the usual larval overwintering strategy and instead persist as dormant adults through the cold months. Normally the last of the season's brood survive as larvae until the next season, but in certain areas the adults remain inactive over winter. Because individuals can live for several months, this adult dormancy lets them outlast the colder season and resume activity when conditions improve.
• The underside of the forewing displays a striking blue eyespot set against a black background, with a bright yellow band framing it above and below. This vivid marking contrasts sharply with the rear wing, which is coloured in various shades of brown and covered in irregular, cryptic patterns that help conceal the butterfly when its wings are closed.
• The yellow admiral is a medium-sized butterfly with a wingspan of 48 to 50 mm in Tasmania and 48 to 55 mm in New Zealand. Wing length varies regionally across its range.
