Eastern-Tailed Blue

The results from our butterfly count of Saturday, July 20, 2013 are now posted. The number of individuals was much higher than 2012, a drought year. Eastern Tailed-Blue, Cupido comyntas, was present in large numbers, including the mating pair pictured below. The Eastern Tailed-Blue feeds on legumes. Locally, the legumes are thriving with the higher precipitation in 2013. In 2012, legumes were stressed by a late freeze in mid-April. The freeze was followed by drought from June to early August. Alfalfa, (a typical legume) was much lower in quantity in Indiana in 2012 as a result. Quality of host plant is one factor that could lead to the second highest count in 10 years.
