Two-spot fritillary (Brenthis hecate) is a medium-sized representative of the pearl-bordered fritillaries family. The uniform orange color of the upper side of the male's wings is interrupted by a pattern of black lines, spots and a black edge. The pattern on the upper side of the wings in the two-spot fritillary is similar to that of the other two species of this genus that live here, but it is not as pronounced.
The female is typically noticeably larger than the male and has a sturdier abdomen. On the upper side it is more mottled, yellowish and orange, and the black pattern is more or less the same as in the male, but somewhat more pronounced.
The underside in both sexes is ochre-yellow with orange markings and irregular black lines, black veins and two rows of black spots along the outer edge of the hindwing pair, from which the species also got its name.
The two-spot fritillary is a resident of lush, flowering meadows, where it often stays near shrubs or forest. In our country it is relatively common; we will notice it on both moist and dry meadows from the lowlands nearly to the forest edge in hilly regions.
