Skin-piercing moths

Definition

Adult moths that use specialized, sclerotized proboscises to pierce vertebrate skin and feed on blood, tears, sweat, or other bodily fluids; a functional grouping within several unrelated moth families rather than a monophyletic taxon. These proboscises typically bear cuticular teeth or barbs and are reinforced to penetrate keratinized tissue, contrasting with the unarmed, siphoning proboscises of nectar-feeding moths.

Etymology

Descriptive compound: 'skin-piercing' (functional feeding mode) + 'moths' (Lepidoptera adults).

Example

The vampire moth Calyptra thalictri (family Erebidae) uses its barbed proboscis to pierce mammalian skin and feed on blood, while the related genus Calyptra also targets eyes to feed on lachrymal secretions; in Southeast Asia, members of the family Noctuidae in the genus Loxomorpha similarly pierce buffalo and cattle skin to obtain blood.

Synonyms

• fruit-piercing moths (broader, partial overlap)
• vampire moths (subset)

Related Terms

Usage Notes

Distinguish from 'fruit-piercing moths,' a broader category that includes species feeding on intact fruit skin but not necessarily vertebrate tissue; some species do both. The term is functional, not phylogenetic—skin-piercing behavior has evolved independently in Erebidae, Noctuidae, and possibly other families. In field literature, 'vampire moth' usually specifies blood-feeding taxa, while 'tearing moth' or 'lachryphagous moth' specifies tear-feeding behavior.
