Biology
Status: Occasional specimens (the first in 1978), but not established.
Habitat: Not established, but presumably anywhere that the host exists. Currently most likely to be individual/small numbers of accidentally imported specimens.
Host plant: Elms (Ulmus spp.)
Overwintering: Unlikely in the UK.
Food: Unknown (adults presumably on leaves)
Other notes: For more on its separation from Galerucella, see: Buckland, P.C. & Skidmore, P. (1999). Xanthogaleruca luteola (Muller) (Chrysomelidae) in Britain. The Coleopterist 8: 97-99.
