Like other dobsonflies, Chloronia adults are nocturnal and secretive. The best way to collect them is setting up light traps close to streams and rivers. Very little is known about life history of any of the species. Formal studies to investigate voltinism, phenology, food habits, behavior, and more, would certainly provide interesting information to fill huge gaps. Whether species produce more than one generation per year remains an open question.
Some species appear to be restricted to small order streams or to large rivers.
Yet, other species, as the widespread C. mexicana Stitz may be eurytopic. Unfortunately, several species described afterwards bring up the need for a new phylogenetic analysis. At this time only broad conjectures and a few evident relationships may be proposed. Some species pairs, at this time based simply on similarity, may remain as formal sister species after a formal phylogenetic analysis. 9th gonostylus bearing a basolateral process, traits that may well be advanced as synapomorphies.
