Diabrotica lemniscata

LeConte, 1868

Diabrotica lemniscata is a skeletonizing leaf beetle in the Chrysomelidae, described by LeConte in 1868. The occurs in Central America and North America. Like other members of the Diabrotica, it is likely a foliage-feeding , though specific ecological details remain poorly documented. Available information is limited compared to well-studied such as D. undecimpunctata and D. virgifera.

Identification

Diabrotica lemniscata can be distinguished from the more common spotted cucumber beetle (D. undecimpunctata) by differences in elytral markings: D. lemniscata lacks the eleven distinct dark spots characteristic of D. undecimpunctata. The "lemniscata" (meaning "ribbon-bearing") suggests banded or ribbon-like markings, though detailed descriptions of these patterns are not readily available in accessible literature. Accurate identification requires examination of voucher specimens or taxonomic keys.

Distribution

Central America and North America. GBIF records confirm presence in both regions, with distribution records from Middle America and North America.

Similar Taxa

Diabrotica undecimpunctataSimilar size and general body form, but distinguished by elytral pattern: D. undecimpunctata has eleven distinct dark spots on pale wing covers, while D. lemniscata has banded or ribbon-like markings implied by its specific epithet.

Data availability

Diabrotica lemniscata is significantly less studied than agricultural pest . As of the knowledge cutoff, iNaturalist records only 15 observations, and no dedicated ecological or agricultural studies were found in the provided sources. Most information on Diabrotica derives from research on D. undecimpunctata (spotted cucumber beetle) and D. virgifera (western corn rootworm), which are major crop pests.
