Trioza centranthi - Trioza centranthi
Adult length 2.5 to 3.0 mm. Whilst the adults can be very difficult to identify without detailed examination, the reddish larval leaf roll galls on Valerian are quite distinctive.
Wherever Valerian, the larval foodplant occurs.
Adult all year.
Nymphs form distinctive leaf-roll galls on Red Valerian (Centranthus ruber), but also feed on Valerianella. Adults overwinter on evergreens.
T. centranthi is a historically rare and scattered species that may be increasing in recent years, primarily found near the south coast of England but possibly moving further north.
Rare or under recorded in Leicestershire and Rutland. The Broughton Astley record of 25th October 2016 is believed to be the first for VC55, although the species appears to be extending its range and it may become more common in our area.
