Larval Host Plant Selection and Daily Behavior of the Poweshiek Skipperling

Abstract

Conservation efforts depend greatly on a working knowledge of the species of concern. Little is known about the basic biology of many endangered species regarding their life history information. This is true for the poweshiek skipperling butterfly, whose larval host plant is not yet known for Michigan populations. This is concerning as Michigan is where the least is known about the life history of the poweshiek and where the greatest number of populations are currently. In this study we investigated the larval host plant by following the butterflies in the field to observe egg laying events. This critical information will be helpful in the future conservation action taken to save the Poweshiek from extirpation from Michigan sites. We also conducted a daily activity budget survey for the Poweshiek. The results from these surveys will be used to provide suggested alterations to the ongoing population surveys that the Michigan Natural Features Inventory is conducting.
