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.
