Chloronia is a genus of dobsonflies in the family Corydalidae.[1]

Description

Chloronia is one of the three New World dobsonfly genera, the other two being Platyneuromus and Corydalus. Chloronia are easily distinguished by their bright yellow coloration with black spots and are present from Northern Mexico south to Eastern South America.[2] Chloronia frequently inhabit the same streams as Corydalus but prefer slower moving waters.[3] Their larvae are distinguishable by their dark head and four dark spots on their pronotum.[4]

Ecology

Species in the genus are attracted to light, especially UV light and most museum specimens have been caught using this method. They are found near running water, but they do not seem to have a preference for width of the river, as they have been found by rivers of 1–20 meters, though there may be more specific preferences for certain species such as possibly Chloronia hieroglyphica. The larvae are predatory as in other Megaloptera and are hypothesized to feed on larvae in the genus Simulium.[5]

Taxonomy

Chloronia contains the following 18 species as of 2026:[6]
