The distribution of this bisexual form is not sufficiently known due to the difficulty of this genus, but it is generally believed that this species has a much wider distribution during all time periods.
Consensus about D. lazuri and D. lichenella is unclear for the moment, it may be about one species that has adopted different biology in different populations.
One generation a year: from March till April.
The larva lives on lichens and mosses growing on tree-trunks, rocks and old walls.
Forests, gardens, and parks.
