Diabrotica
genus of leaf beetles

Diabrotica is a large, widespread genus of beetles in the family Chrysomelidae. Members of this genus include several destructive agricultural pest species, sometimes referred to as corn rootworms.
There are an estimated 400 species grouped into the genus Diabrotica. Within Diabrotica there are 3 series: fucata, virgifera, and signifera groups. The fucata series contains the majority of Diabrotica diversity with 354 species. Fucata are characterized as multivoltine, producing two broods of offspring per year. The virgifera series comprises 24 species, and the signifera series contains 11. Additionally, virgifera and signifera are characterized as univoltine, and will only brood one set of offspring annually.
There is very limited information on most species of Diabrotica. Majority of the research conducted on the Diabrotica genus focuses on investigating species of consequential economic importance, such as D. balteata, D. barberi, D. undecimpunctata howardi, D. virgifera, D. speciosa.
Begin with the source’s own compact description: “Diabrotica” is genus of leaf beetles. The dossier treats that line as a proposition to test through Diabrotica, genus and leaf, not as a finished interpretation.
Why this record matters
The phrase “genus of leaf beetles” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 7, 2026. The linked authority identifier is Q1937630. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
