Callophrys henrici

[paul opler]

Hi Kathryn,

You will find a good write-up in my book Butterflies East of the Great 
Plains. 1983. Johns Hopkins University Press.

There is also a map of county records and a species account on the USGS 
Butterflies of North America web site.  To my knowledge it is 
single-brooded throughout its range which does not include the Lower Rio 
Grande valley or northern Mexico.

Anne Swengel of Baraboo, Wisconsin has done some population studies of 
henrici in recent years.

Best wishes,

Paul Opler, Professor
Colorado State University
