Ancylolomia laverna

Definition
Ancylolomia laverna is a species of moth in the family Crambidae, belonging to the genus Ancylolumia.

Overview

• Taxonomic hierarchy:

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Class: Insecta
  • Order: Lepidoptera
  • Family: Crambidae
  • Subfamily: Crambinae
  • Genus: Ancylolomia
  • Species: A. laverna

• Authority: The species was first described by George Hampson in 1899.

• Distribution: Records in taxonomic databases (e.g., GlobIZ, Catalogue of Life) list the species from the Indian subcontinent, with confirmed occurrences in India and Sri Lanka.

• Habitat: Like other members of the genus, A. laverna inhabits grassland and open‑field environments where its larval host plants are grasses.

Etymology/Origin

• The generic name Ancylolomia derives from the Greek words ankylos (“curved”) and lomia (“border” or “edge”), referring to the characteristic shape of the forewing margins in many species of the group.
• The specific epithet laverna is likely taken from the Latin “Laverna”, the name of the Roman goddess of thieves, a naming convention occasionally used in Lepidoptera to provide a distinctive, memorable label. The original author did not publish an explicit explanation.

Characteristics

• Adult morphology: Adults exhibit the typical Crambinae “snout‑moth” appearance, with elongated forewings bearing longitudinal streaks of brownish‑gray coloration that blend with the surrounding grasses. The wingspan is estimated at 20–30 mm, a size range common for Ancylolomia species.
• Wing pattern: The forewings display a series of dark, narrow transverse lines and a subtle, pale median band; hindwings are generally lighter, often whitish‑gray.
• Life cycle: Larvae are believed to be stem‑borers of grasses, feeding internally and emerging to pupate within silken shelters near the ground. Detailed life‑history studies for A. laverna have not been published.
