| The butterfly species in
bold have been seen in Berks County, Pennsylvania in 2010. There are
records of 108 species for Berks County. The list below includes all those
reported from 2003 through 2009, a total of 87 species. New species (not
seen during 2003 - 2009) will be added in

No doubt other species
will be present, but not seen. Some of the 108 species are historical records

been seen in the past 40 years. Two species were added to this list in
2009.
