I am a large butterfly with a wingspan of 7-8 cm. My name comes from my coloration that is deep purple-blue depending on the light (in the males). I have a large white band on the underside of my hindwings.
I do not have a traditional diet. I feed on the sap oozing from trees or the honeydew secreted over the foliage by aphids. My menu also includes fresh droppings as well as carrion and basically anything that grabs my sense of smell.
I lay my eggs on the leaves of host trees like willows or poplars.
Where and when can you find me in the reserve ?
I live in wet forests, along the forest edge, in clearings and along footpaths.
When to spot me
Like all reptiles in our latitude, I hibernate in the cold months so you can spot me between March and October.
Did you know?
You can find me between June and August.
