They are is similar to Sympetrum species in appearance and behavior in some cases. Because species within this genus are similar-looking and change in appearance as they age, careful observation and considerable practice is required to correctly identify both genders of various ages of all species.

Shading illustrates monthly percentages of the total flight season records for the species. Each flight season record is a unique date/location/observer combination where one or more adult or an exuvia was recorded (excludes nymphs). The actual number of flight season records for each month is shown in parentheses.

Flight seasons begin earlier in the southern part of the state, often by a week or more. Also, flight charts may not be accurate for rare species because of few data available.
