Definition
Herpetogrammatini is a tribe of moths within the family Crambidae, subfamily Spilomelinae. The tribe groups together a number of closely related genera, most notably Herpetogramma.
Overview
In the hierarchical classification of Lepidoptera, Herpetogrammatini occupies the following rank:
- Order: Lepidoptera
- Superfamily: Pyraloidea
- Family: Crambidae
- Subfamily: Spilomelinae
- Tribe: Herpetogrammatini
Members of this tribe are distributed worldwide, with a concentration of species in temperate and tropical regions of the Americas, Asia, and Oceania. The tribe comprises several genera that together include dozens of described species. Adults are typically small to medium-sized moths, and many species are nocturnal and attracted to light. Larvae of several genera are known to feed on a variety of plant hosts, often as leaf‑rollers or miners.
Etymology/Origin
The name Herpetogrammatini is derived from the type genus Herpetogramma—itself formed from the Greek words “herpeto‑” meaning “creeping” or “reptile” and “gramma” meaning “line” or “mark”—combined with the zoological suffix “‑ini,” which denotes a tribe.
Characteristics
Taxonomic characters that define Herpetogrammatini include:
- Wing morphology: Forewings usually display a distinctive pattern of transverse lines and spots; the venation pattern conforms to typical Spilomelinae traits, with a well‑developed discal cell and specific branching of veins R₁–R₅.
- Genitalia: Male and female genital structures exhibit consistent features across the tribe, such as a bifurcated uncus in males and a signum of characteristic shape in the female corpus bursae, which are used in diagnostic keys.
- Larval behavior: Many larvae construct silken shelters by rolling or folding leaves of their host plants; some are leaf miners in early instars. Host plants span several families, including Poaceae, Asteraceae, and Solanaceae.
- Life cycle: Species generally undergo complete metamorphosis with one to several generations per year, depending on climate and latitude.
