Lytta Fabricius 1775
From Greek lytta, lyssa (λυττα, λυσσα) 'madness, rage' (refers to the toxic properties of these beetles)
47 spp. in 4 subgenera in our area(1), ~70 in the Nearctic Region(2), ~110 total (arranged into 9 subgenera)(3); 3 spp. in the northeast (L. aenea, L. sayi, L. unguicularis)(4)
7-27 mm
