Hydriomena deltoidata
In 3 days ~20% in a week ~40%
Hydriomena deltoidata is a species of moth in the family Geometridae. It was first described by Francis Walker in 1862. This species is endemic to New Zealand. The classification of New Zealand endemic moths within the genus Hydriomena is regarded as unsatisfactory and in need of revision. As such this species is currently also known as Hydriomena (s.l.) deltoidata. The adults of this moth are known to pollinate Dracophyllum acerosum and Leptospermum scoparium. Wikipedia →
