Argynnis aglaja
Fairly common & widespread Butterfly all over Britain.
The Caterpillars are similar to the High Brown Fritillares.
The Larvae also feeds on Violets.
The large Fritillary is fiery reddish yellow above, the basal area of the Male being always duller.
The markings are constant: a black margin, a row of deep black but thin marginal arcs, a very straight, central row of dots.
The underside of the hindwing is characteristic; it bears numerous silver-spots on a partly verdigris partly leather-yellow ground, but never a row of ocelli in the marginal area.
Flight period is from July-September.
