"L. lineolaris" is most commonly found in the eastern half of North America. A study done to track the genetic diversity and overall distribution of "L. lineolaris", specifically on host plants, in North America sampled three separate populations of "L. lineolaris" and marked their DNA with mitochondrial genes cytochrome oxidase 1 and cytochrome oxidase 2. The researchers wanted to examine whether the genetic differences found between "L. lineolaris" species were based on geographical factors. The results indicated significant differences in mtDNA among "L. lineolaris" species found across North America. Other evidence indicated that "L. lineolaris" species were found consistently on the same plant hosts but showed no specific preference for plant hosts.
