The Purple Lesser Fritillary is one of many rare species featured in our Unique Areas Brochure. This butterfly, native to northern regions, gathers in the forests of Northern Maine in an area in which J.D. Irving, Limited (JDI) conserves as a part of our Unique Areas Program.
The sparse, windy area of Northern Maine mimics the climate of the north, providing the perfect growing conditions for the plant on which the Fritillary lays its eggs – the Dwarf Willow. As one of the world’s smallest woody plants, the Dwarf Willow grows only 1-6 centimeters above the ground. The Purple Lesser Fritillary larvae feed on the Willow while adults lay their eggs on the backside of the leaves.

As a state-threatened species, conserving the Purple Lesser Fritillary and its habitat is especially important to JDI. This sighting is the only known modern occurrence of the species in Maine.

• Birds & Mammals
