Lesser Marbled Fritillary (Brenthis ino<\/em>)<\/h3>\n\n\n\n

The Lesser Marbled Fritillary<\/strong> is a medium-sized, graceful butterfly belonging to the family Nymphalidae<\/strong> (the brush-footed butterflies). Although not as well-known as some of its larger fritillary relatives, it is admired for its delicate marbled wing pattern and its preference for moist, flowery meadows and forest edges.<\/p>\n\n\n\n
