Although the Diana Fritillary has a relatively large range and there may be approximately 100 occurrences, it has undergone a steep decline and climate change alone is likely to reduce this species' habitat by about 90% by 2050.
The US states where the butterfly remains carry the following conservation ratings:
Indiana & Ohio - Presumed extirpated (SX)
Alabama, Arkansas, Oklahoma, Kentucky, West Virginia - Imperiled (S2)
Tennessee, Virginia, North Carolina, South Carolina, Georgia - Vulnerable (S3)

According to the Xerces Society, the Diana Fritillary is susceptible to habitat change. Historically, it was more widespread and likely more abundant within its range. Land clearance in the nineteenth and twentieth centuries reduced the overall range and virtually eradicated the Diana fritillary from the Ohio Valley, eastern Virginia, and eastern North Carolina. Records for Indiana, Maryland, Ohio, and Pennsylania are almost all from the nineteenth century or earlier.
