Cerodontha iraeos (Robineau-Desvoidy, 1851)
< back | next >
makes short blotch mines


Food Plant: Iris pseudocorus (Yellow Flag)

Mine: July - August

Pupa: in the mine

Notes: Short, longitudinal blotches - often coalescing to make longer mines or wider mines or both (count the larvae). Mines on other species of Iris are almost certainly Dizygomyza iridis and not this species. Widespread and common throughout the U.K. in association with its host, also Scilly Isles and Tipperary, Ireland. Most northerly Scottish record - Banff ; Inner Hebrides, (Isle of Coll). Formerly Dizygomyza iraeos
