It’s true, fairies do live in the woods …
The Green Long-horn, Adela reaumurella is a small day-flying micro-moth belonging to the family Adelidae, the fairy longhorn moths. They have a wingspan of approximately 14 to 18 mm. The forewings of both sexes are a beautiful metallic blue-green, sometimes with a slight golden tinge, their hindwings metallic bronze. The males have extremely long white antenna and have rough black hair on their heads. In comparison, the females have relatively short white-tipped black antenna with shorter and lighter hair on their heads. It is a fairly common species in England and Wales though more localised elsewhere. They typically fly from April to June where they can often be observed ‘dancing’ in swarms.
They are simply gorgeous …
