Hypera pollux (Fabricius, 1801)
Found on Apium nodiforum (Fool's Water Cress) growing along drainage ditches and slow moving water courses, Hypera pollux visually resembles several other species of Hypera. Knowing the foodplant can help considerably with identification, but this seems to be a rare find in Nottinghamshire. Having said that, Hypera pollux will probably be abundant wherever it occurs. We found both larvae and the 'cage-like' cocoons to be numerous in a ditch near the Railway Pit at Hoveringham, in late July 2017. All the pupae we originally collected, proved to be parasitised, so a return trip was needed to photograph the adults.
