Full-Year Compilation for 2016

This dusted skipper found and photo'd by Jack Miller on 5-18-16 near Shaw's Mill Road, CUM, was our FOY for 2016.

This dusted skipper found and photo’d by Jack Miller on 5-18-16 near Shaw’s Mill Road, CUM, was our FOY for 2016.

Jack Miller has done it again. Following up on his compilation for 2015, here is his full-year compilation of species, reports, and individuals as posted on our Sightings Log, January-December, 2016.  He worked on this through the fall (while he was also working on the 2015 compilation) and completed it in the first couple of days in the New Year.

Thank you, JM!

Here’s his report:

 

About the 2016 Compilation:

In 2016, the log recorded 91 species for 78,133 butterflies in 3184 reports.  In simple terms, this means there will not be a recount despite the likelihood that some mistakes have been made while compiling this massive amount of data.  Please report any significant errors you might discover.

There were 13 species that recorded new FOY’s and 25 species that either tied or set new LOY’s.  Three species — gray hairstreak, viceroy, and southern cloudywing — set both new FOY’s and new LOY’s.

This compilation does not include reports designated as “species” such as “anglewing species” or “azure species.”

Thousands of butterflies were left out of the compilation as there was no uniform way to include the approximately 150 reports of “C, A or S” (common, abundant, or superabundant).  Due to this, a few species like cabbage white, orange sulphur, eastern-tailed blue, buckeye, sachem, and broad-winged skipper are under-reported by many thousands, especially during their peak times of appearance.  On the other hand, some species are significantly over-reported.  It appears that there are three main factors  that can create a situation for over-reporting:

1) some species may only be found in one or a few places and the same bugs get counted numerous times over a short flight period (notably little yellow, sleepy orange, bronze copper, hoary elfin, meadow fritillary, mulberry wing, and Dion skipper);

2) some species appear in reporters’ gardens and the same bug gets reported many times over the course of its stay (notably Hayhurst’s scallopwing, banded hairstreak, painted lady, red-spotted purple, and tawny emperor);

3) lastly, some species may be found in a spot that is especially frequented by enthusiasts who are logging (notably Appalachian brown, Peck’s skipper, and northern broken-dash).

This compilation does not necessarily pretend to present “good” science, although much valuable information is present that in the hands of researchers could be of much value.  The article “Climate-driven Changes in Northeastern US Butterfly Communities by Breed, Stichter and Crone states the following: Natural history observations by amateurs have the potential to document the distribution and abundance of species in places where systematically collected monitoring data do not exist.

Please enjoy this compilation and let it be an inspiration to stimulate thinking, questioning, and an urge to get outside.
