Novel host associations and habitats for Senecio-specialist herbivorous insects in Auckland
We studied the genus- and species-specialist monophagous herbivorous insects of Senecio (Asteraceae) in Auckland, New Zealand. With the exception of the widespread S. hispidulus, the eight native Senecio species in mainland Auckland (two endemic) are typically uncommon and restricted to less modified conservation land. However, 11 naturalised Senecio have established and are often widespread in urban and rural habitats.
