Diaphania infimalis

Guenée, 1854

Diaphania infimalis is a small crambid described by Guenée in 1854. It occurs across the Caribbean, Central America, and northern South America, with a northern extension into Florida. Forewing length ranges 9–10 mm in males and 9–11 mm in females. Larvae have been documented feeding on Melothria grendula.

Identification

Differs from congeneric () and () by geographic distribution and subtle wing pattern differences; precise distinguishing characters require examination. The smaller size and more southerly Caribbean-Central American range may aid separation from North American Diaphania .

Appearance

Small with forewings measuring 9–10 mm (males) or 9–11 mm (females). As a member of Diaphania, it likely exhibits the translucent wing patches characteristic of this group, though specific pattern details for this are not well documented in available sources.

Habitat

Associated with plant Melothria grendula; likely occurs in tropical and subtropical environments where this plant grows. Specific preferences beyond host association remain undocumented.

Distribution

Florida (USA), Mexico, Guatemala, Belize, Bahamas, Cuba, Jamaica, Panama, Venezuela, and Bolivia.

Diet

Larvae feed on Melothria grendula (Cucurbitaceae). feeding habits are unknown.

Host Associations

Melothria grendula - larval food plantOnly documented ; relationship established through larval feeding records

Similar Taxa

Diaphania nitidalis is congeneric and occurs in overlapping regions; D. infimalis is smaller and has more restricted Caribbean-Central American distribution versus broader North American range of D. nitidalis
Diaphania hyalinata is larger congeneric with similar translucent wing appearance; D. infimalis has smaller forewings and more southerly distribution

Taxonomic Note

GBIF lists this as a synonym under Cryptographis infimalis, indicating ongoing taxonomic uncertainty or recent reclassification proposals. The Diaphania placement follows current Wikipedia and iNaturalist usage.

Research Context

While congeneric D. nitidalis and D. hyalinata are well-studied agricultural pests of cucurbits, D. infimalis has received minimal research attention and lacks detailed biological studies beyond basic distribution and records.
