During this time, the caterpillars are highly dependent on the availability of wild lupine. A decline in this plant species directly impacts the caterpillar’s survival.
Pupal Stage
After feeding sufficiently, the larvae enter the pupal stage. They create a chrysalis, often camouflaged among vegetation. This stage can last from one to two weeks, depending on environmental conditions. During this time, significant transformations occur as the caterpillar develops into a butterfly.
Adult Stage
The adult Karner Blue Butterfly emerges with vibrant blue wings in males and orange-brown wings in females. The lifespan of an adult butterfly varies but generally lasts around one month during the summer months. Adults are active during warm weather and are particularly attracted to flowering plants for nectar.
