Paranaemia vittigera
(Mannerheim, 1843)
Broad-striped Lady Beetle
Paranaemia vittigera, the broad-striped lady beetle, is the sole described in the Paranaemia. It is native to western North America and has been introduced to Hawaii. Unlike the familiar spotted ladybugs, this species displays longitudinal stripes rather than spots. It preys on aphids and has been documented visiting flowers, particularly the California poppy.

Identification
Distinguished from other Coccinellidae by its striped (vittate) elytral pattern rather than spotted or blotched markings. The Paranaemia is , with P. vittigera as its only described . Striped pattern separates it from common spotted lady beetles such as Hippodamia and Coccinella species.

Habitat
Found in association with flowering plants; documented on California poppy (Eschscholzia californica) in California. Specific preferences beyond floral visitation are poorly documented.
Distribution
Native to western North America; introduced to Hawaii. Documented from northern California including the Central Valley, with museum specimens from across the region.
Seasonality
active in spring; observed in March in California.
Diet
Preys on aphids.
Behavior
Visits flowers, particularly California poppy. Flower-visiting observed in spring.

of aphids; contributes to of .
Human Relevance
Used as an example of lady beetle diversity in educational contexts; subject of citizen science observation through iNaturalist and the Lost Ladybug Project.
Similar Taxa
- Hippodamia speciesSimilar body form but spotted rather than striped elytral pattern
- Coccinella speciesCommon spotted lady beetles with rounder body and spotted pattern
- Other striped CoccinellidaeSome other (e.g., certain Coleomegilla) may have stripes, but differ in body proportions and stripe configuration
Misconceptions
Often mistaken for a non-lady beetle due to its striped pattern; many people associate ladybugs exclusively with red coloration and black spots.

Taxonomic note
Originally described as Hippodamia vittigera by Mannerheim in 1843; transferred to Paranaemia. The genus name reflects its distinctiveness from other Coccinellidae.
Research gaps
Biological information is limited despite the being native and relatively widespread in western North America. , larval , and detailed associations remain poorly documented.
