Bionomics
The caterpillar makes a lot of small holes in one leaf. The case is gradually enlarged giving it a rough triangular view. The rings are cut out of the lower epidermis. The larva is fully developed in the autumn of the second year of its development. Hence, the larval stage lasts two years.
Flight periods
From the end of May and especially the entire month of June.
