Altica lythri is a species of flea beetle from the leaf beetle family, that is common in Asia, Europe, and North Africa, including Israel.
[1] The beetles size is 5 mm (0.20 in), and their colour is blue with black and green.
[4] The species hibernate in winter, and come aground during summer months, when they are hungry.
They feed on leaves of willowherb, water primroses[5] and sallows.
[6] The species could become victims of such predators as Braconidae, Ichneumonidae, and adults of Pentatomidae, especially Zicrona caerulea.
