Butterfly of the Week: Peck's Skipper

Peck's Skipper

Polites peckius (Kirby 1837)
Status: Common breeding resident

Flight: Two distinct broods in Iowa. Adults are most commonly seen from late April to October. A single early October collection suggests that a partial third brood may fly in some years.

Distinguishing features: This small skipper has a distinctive patchwork of light yellow on the underside of the hind wing, unlike any other skipper in the state. Wingspan: 2.5 cm. (males), 2.7 cm. (females).

Distribution and habitat: Map 180. One of Iowa's most abundant skippers, found in a wide variety of human-altered and natural open habitats across the state. It is often seen along creeks and in permanent pastures.

Natural history: Peck's Skipper exhibits some degree of phenotypic variability in its markings. For instance, the hind-wing undersurfaces on some specimens do not have clear-cut spots but instead form a large yellow patch reminiscent of the Whirlabout (Polites vibex [Geyer 1832]). In fact, the few records of the Whirlabout from the state likely represent this form. While Peck's Skipper has been reared on a number of different grasses in the laboratory, it apparently commonly feeds on rice cut-grass and panic grass in nature.

Questions: What food plants are utilized by the larvae in Iowa? Is the variability in wing appearance (spot pattern, size, etc.) more controlled by genetic or by environmental factors? Are adults preferentially attracted to particular flower colors or shapes?

Interview with Leigh Adcock, Part 1

In developing the press’s new list in food studies, acquisitions editor Catherine Cocks is talking to people who are active in the field. Recently, she spoke with Leigh Adcock, the executive director of the Women, Food, and Agriculture Network, about her organization and its aims.

Catherine: According to your website, the Women, Food, and Agriculture Network exists to enable women in sustainable agriculture to talk with each other about the issues they face. Why do women need an organization of their own?

Leigh: As in other male-dominated fields, women in agriculture often prefer to network and learn from one another in an organization dedicated to them. Other women-in-ag networks exist for those engaged in more traditional commodity-based farming; WFAN is one of a small number of networks around the United States dedicated to women engaged in small-scale, diversified farming. We are the only one that engages in leadership development and policy advocacy on a national level.

Catherine: What are some of the issues that concern your members the most?

Leigh: Our last member survey showed that most women in sustainable ag are concerned about affordable health care for their families. That was the biggest barrier to success as small-scale farmers. Beyond that, their other concerns are similar to those of other farmers—access to land and capital.

Catherine: Since the informal founding of WFAN in 1994, the local/sustainable/organic food movement has grown exponentially. How has this growth affected women farmers and landowners?

Leigh: As the movement has grown, our membership has grown along with it. When I started as WFAN’s executive director in 2008, we had about 300 members, mostly in Iowa and neighboring states. Today we have nearly 3,000 members from all states and several other countries. Our operating budget has grown as well, as we expand our programming to meet the increased demand for networking, education, and leadership development opportunities for women in the movement. The healthy food and farming movement has been a women’s movement from the beginning—women operate the farms, buy the food, and staff the nonprofits that support the movement.
