A second summer survey of our medium and slow phenology Karner Blue long-term monitoring sites here. On July 17 we saw 46 Karner Blues in more hours of surveying than we did today. Today 70% of the 64 Karner Blues for which we could tell the gender were males; on July 17 the ratio was 93% males/7% females. The Marine Blue and almost half of the Karner Blues were along Stanton Creek Road.
