Cecrita is a of prominent moths in the Notodontidae, established by Francis Walker in 1855. The genus contains approximately eight described distributed across North, Central, and South America. These are part of the Heterocampinae. Two species, Cecrita guttivitta (saddled prominent) and Cecrita biundata (wavy-lined heterocampa), are relatively well-known and frequently encountered.

Identification

Cecrita can be distinguished from related in Heterocampinae by wing pattern and genitalia . The saddled prominent (Cecrita guttivitta) displays a distinctive dark saddle-shaped marking on the forewings. The wavy-lined heterocampa (Cecrita biundata) shows two undulating transverse lines across the wings. Accurate identification to species level generally requires examination of genitalia or reference to original descriptions, as external morphology can be subtle and variable.

Distribution

North America, Central America, and South America. Specific distribution varies by ; Cecrita guttivitta and Cecrita biundata are broadly distributed in eastern and central North America, while Cecrita cubana occurs in Cuba and associated regions.

Ecological Role

Larvae of prominent moths in Notodontidae function as herbivores, consuming foliage of woody plants and contributing to nutrient cycling in forest . serve as prey for bats, birds, and other .

Human Relevance

The saddled prominent (Cecrita guttivitta) is occasionally recognized as a forest pest, with larval causing defoliation of hardwood trees. The is also used in ecological research on and phenological responses to climate change.

Similar Taxa

  • DisphragisGBIF lists Cecrita as a synonym of Disphragis, reflecting historical taxonomic uncertainty; current treatments (Catalogue of Life, recent revisions) maintain Cecrita as valid based on distinct morphological characters.

Taxonomic History

The has undergone recent revision. Miller (2021) described two new (Cecrita franclemonti and Cecrita plumosa) and clarified boundaries between Cecrita and related genera. The GBIF synonymy with Disphragis appears outdated and not supported by current authoritative sources.

Research Significance

Cecrita guttivitta has been studied for its response to climate change, with observations of shifting and range expansion. The serves as a model group for understanding diversification in Nearctic faunas.
