Mulsantina quinquelineata
Five-lined Lady Beetle
Mulsantina quinquelineata, known as the Five-lined Lady Beetle, is a of lady beetle in the Coccinellidae. It is distinguished by the five dark longitudinal lines on its , a pattern unusual among North American coccinellids. The species is relatively poorly documented, with few published observations. It belongs to a characterized by elongated body forms compared to the more rounded typical lady beetles.

Identification
The five longitudinal stripes on the are diagnostic and separate this from all other North American Coccinellidae. Most lady beetles have spots, transverse markings, or solid colors rather than longitudinal lines. The elongated body form is shared with other Mulsantina species but the specific line pattern distinguishes M. quinquelineata from such as M. picta (which has transverse markings).
Habitat
Associated with coniferous forests, particularly pine-dominated . Found on pine foliage and branches where prey occur. Specific microhabitat preferences within forest systems are not well documented.
Distribution
North America; documented from the southeastern United States. Range appears to be restricted and poorly sampled, with most records from pine forest regions.
Ecological Role
Presumed to function as a of conifer-feeding aphids and other small Hemiptera, based on association and -level traits, though direct observations of feeding are not documented.
Similar Taxa
- Mulsantina pictaShares elongated body form and pale coloration, but has transverse dark markings rather than longitudinal lines.
- Other CoccinellidaeMost North American lady beetles have spotted or transverse patterns; the longitudinal stripe pattern is unique to this .

Taxonomic Note
The Mulsantina was historically treated as a subgenus of Coccinella but is now recognized as distinct based on morphological and molecular data. The specific epithet 'quinquelineata' refers directly to the five-lined pattern.
Data Deficiency
This is among the most poorly documented North American coccinellids. The low observation count (4 records on iNaturalist as of source date) reflects genuine rarity, restricted range, or under-sampling of conifer rather than identification difficulty.
