Heliconians are sometimes divided into two groups according to their size. All of genus Boloria Heliconians belong in the “small” group. Titania’s fritillary is extremely rare and is perhaps easiest to recognize from the mainly brownish violet colour on the underside of the outer parts of its hind wings, and the edge has a row of arrow-shaped (v-shaped) marks, inside which there is a row of spots with partly white centres.

Females lay their eggs individually on or close to the host plant. Titania’s fritillary overwinters as a small caterpillar, and begins to eat only when spring arrives.
