Results BTA butterfly count, Sep 10th, 2011
Tuesday, September 13, 2011
Presumable because of the double freeze this winter and the extremely hot and dry summer, the butterfly numbers were way down from 2010. This is a trend we are seeing thoughout Arizona. Last year we found 44 species of butterflies on just the BTA property on count day (a new record!), while this year it yielded only half of that: 22 species. But we had fun nonetheless, partly because it was the first day with nice fall temperatures, and also because we had guests from Tucson and from England help us with the count! Other teams added species elsewhere in the count circle for a total of 42 species, 514 individuals.
