Annual SWBA Field Trip. Lowest species numbers of the 7 years this field trip has been conducted. Nevertheless, we found all 5 Elfins! If we ignore the highly anomolous hot spring of 2012, we have previously averaged 21 species and 232 individuals, but this year we found only 13 species and 85 individuals. The exceptionally cold spring continues to depress butterfly populations.
