Gomphidae, Clubtail Family
"Most Wanted" Species


Global: G5     Wisconsin: S3S4    

Distinguishing Characteristics:

The jade clubtail's thorax is grayish jade green with brown shoulder stripes. The abdomen has gray-green rings except near the end, when it becomes dark brown with a flare. The eyes are green with thighs and shins pale. The body length ranges from 2.0 to 2.2 inches.

Description of Habitat/Range:

This species can be found throughout mid-United States in mud-bottomed ponds, sloughs, and lakes. It seems to be associated with Mississippi River flythrough. It is known in Wisconsin, only from two southern counties.

Flight Season:

Throughout its range, the flight season is from late April to early August. In Wisconsin, the typical flight season is mid-June to early August.

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.
