Diabrotica er en artsrik slekt av biller som tilhører familiegruppen bladbiller (Chrysomelidae). Det er kjent 370 arter.Rui-E Nie, Jan Bezdek & Xing-Ke Yang (2017) How many genera and species of Galerucinae s. str. do we know? Updated statistics (Coleoptera, Chrysomelidae). ZooKeys 720: 91-102.
Utseende Middelsstore (4–9 millimeter), ovale, blanke bladbiller, ganske variable i fargen, gulaktige eller lyst grønnlige til svarte, gjerne med svarte tegninger, oversiden ikke påfallende punktert og uten synlige hår. Pronotum er avrundet firkantet, mye smalere enn dekkvingene, som er noe utvidet bakover. Beina er tynne, middels lange, gule til svarte.
Levevis Både larvene og de voksne (imago) er planteetere, ofte på busker og trær. Noen av artene kan opptre i store mengder og snauspise vertsplantene i enkelte år. De voksne billene flyr godt og kan forflytte seg over betydelige avstander. Noen av artene er alvorlige skadedyr på mais.
Utbredelse Slekten er utbredt i Amerika. Diabrotica virgifera har blitt innført til Europa European and Mediterranean Plant Protection Organization (2012) Situation of Diabrotica vigrifera virgifera in the EPPO region (2012) Besøkt 28.6. 2019 der den først ble registrert i Serbia i 1992, den antas å ha blitt innført med amerikanske troppetransporter under krigene i Jugoslavia på 1990-tallet.
