Zweipunkt-Eulenspinner

<em>Ochropacha duplaris</em>, the common lutestring, is a moth in the family Thyatiridae distributed across Belgium, Denmark, Norway, and Sweden. It is classified as Least Concern on the IUCN Red List, indicating stable populations across its European range. This species is typically associated with deciduous woodland habitats where its larval host plants, primarily birch and alder trees, are abundant. The moth exhibits characteristic wing patterning with subtle brownish tones and distinctive cross-lines, providing camouflage when at rest on bark. Adults are nocturnal and are typically observed during summer months. Larvae feed on the leaves of host trees, completing their development before pupating in leaf litter or soil. The common lutestring is one of several species in the Thyatiridae family found across northern Europe, where temperate broadleaf and mixed forest habitats support stable populations. Biological traits beyond diet and habitat preferences remain relatively limited in available documentation for this species.
