Cilix is a genus of moths in the family Drepanidae, subfamily Drepaninae, commonly referred to as hook‑tip moths. Species of this genus are distinguished by a characteristic hook‑shaped tip on the forewings and a resting posture that often mimics dried leaves or twigs, providing camouflage against predators.
Taxonomic classification
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Lepidoptera
- Family: Drepanidae
- Subfamily: Drepaninae
- Genus: Cilix
The type species for the genus is Cilix glaucata, known as the “European hook‑tip.” Other species recognised within the genus include Cilix asiatica, Cilix patula, and Cilix pulcher, among others.
Distribution
Members of Cilix occur across temperate and subtropical regions of Europe, Asia, and parts of North Africa. C. glaucata is widespread throughout Europe and extends into the western Palearctic region.
Life history and ecology
- Larval host plants: Larvae feed primarily on plants in the families Salicaceae (willows) and Populus (poplars).
- Adult behavior: Adults are nocturnal and are commonly attracted to artificial light sources. Their wing shape and coloration provide effective camouflage when at rest on tree bark or foliage.
Research relevance
Species of Cilix are frequently cited in entomological studies focusing on wing morphology, camouflage strategies, and phylogenetic relationships within Drepanidae.
