Lantana

Definition

A genus of approximately 150 species of perennial flowering shrubs and herbs in the verbena family (Verbenaceae), native to tropical Americas but widely introduced and invasive in tropical and subtropical regions worldwide. In entomological and ecological contexts, Lantana is notable as a significant host plant for specialist herbivorous arthropods and as an ecological disruptor in invaded ecosystems.

Etymology

From Late Latin, originally applied to Viburnum lantana (a distantly related shrub), possibly from Greek lanthanō ('to escape notice, to be hidden'); transferred to the American genus by Linnaeus.

Example

The lantana lace bug (Teleonemia scrupulosa) was introduced to Australia from Mexico in 1935 as a classical biological control agent against invasive Lantana camara, which had spread across rangelands and was altering native pollinator and herbivore communities; the bug's population dynamics and host-specificity remain model systems for weed biocontrol research.

Usage Notes

In entomological literature, 'Lantana' most commonly refers to L. camara, the most widespread invasive species. Specialists distinguish between the plant's role as a nectar source (often beneficial to generalist pollinators) versus its status as an invasive weed requiring arthropod biocontrol. The genus should not be confused with Viburnum lantana (wayfaring tree), the etymological source of the name. Arthropod associations vary by region: native-range insects include specialists coevolved with the plant, while invaded-range communities comprise generalist feeders and deliberately introduced biocontrol agents. The plural 'lantanas' typically refers to multiple species or individual plants; 'lantana' as a mass noun describes the plant as vegetation or infestation.
