Agonopterix alstroemeriana (Clerck, 1759). Adventive. Widespread & Common.
Found in a wide range of habitats, including roadside verges, waste ground, marshes, riverbanks and native forest. Single brooded, can be found all year round.
The larval form grows to around 10 mm and feeds on Hemlock (Conium maculatum), in a slight tube in the leaves, sometimes also the flowers. After pupating, the moths emerge from the soil as adults.
Of Palearctic origin, it was first found in North America in 1973 when it was accidentally introduced. The moth is now widespread throughout the northern half of the United States, southern Canada, northern Europe including the UK, and, more recently, New Zealand.
