Species Profile
Dichrorampha senectana is a moth belonging to the family Tortricidae first described by Achille Guenée in 1845.
The Dark Drill faces significant threats from habitat loss and degradation due to agricultural intensification and urban development across its European range. Climate change poses additional risks by altering the distribution and phenology of its host plants, while pesticide use in agricultural areas directly impacts both the species and its food sources.
Key Facts
Habitat & Distribution
Inhabits woodland edges, scrubland, and areas with abundant Artemisia species (wormwoods) where larvae develop within the flower heads and stems of these host plants. Typically found in semi-natural grasslands, chalk downs, and coastal areas with suitable host plant communities.
