Observations of feeding damage of some Turkish leaf beetles (Chrysomelidae) with new masquerade and host plant records

Twenty-three observations of leaf beetles and their feeding damage are reported. Masquerade is found in 15 observations. In 12 observations dark colored beetles were making obvious dark colored damage. Light colored beetles of three species were observed making light colored damage. Masquerade in Chrysomelinae is reported here for the first time. In Galerucinae, masquerade is recorded for the first time for the species of Calomicrus Stephens and Orthocrepis Weise. New host plants are recorded for: Longitarsus hittita Biondi - Anchusa azurea Mill.; Longitarsus audisioi Biondi - Symphytum asperum Lepech.; and Chaetocnema tibialis (Illiger) - Chenopodium rubrum L.
