Gomphurus ventricosus  (Walsh, 1863)
Skillet Clubtail


Gomphidae, Clubtail Family

Status-Global/State:

Global: G3     Wisconsin: S3S4    

Distinguishing Characteristics:

Named for its very wide club, the skillet clubtail varies in its body length from 1.9 to 2.1 inches. The body is green-yellow with black thoracic stripes and black legs. The abdomen and club are black with yellow markings. Clubtail species are very similar to each other in some aspects, careful inspection is needed to identify them.

Description of Habitat/Range:

Rare throughout northeastern United States and southeastern Canada, this species prefers small to large turbid rivers with at least a partly mud bottom but good water quality. Sometimes it can be found at clean lakes with sand or sand-marl (calcium-rich) bottoms. The skillet clubtail is widely distributed in northern Wisconsin, although not necessarily in abundant numbers.

Flight Season:

Late May to mid-August in Wisconsin.

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.
