GTM Occurrence 5

The Little Yellow is considered frequent at the GTM. However, in November, 2009, 111 individuals were observed. This high number of specimens observed during one day skewed the data for this species. In the other years of this study the Little Yellow was only seen during April, May, July, September, October, and December and only in numbers of 1 to 6 individuals per month for Transects A-C.

Most observations were in the open habitat along Transect A. Five specimens have been observed from the Marsh Pond Overlook (Transect B) and only a single individual has been observed from the Red Bay Walk (Transect D). There have been 134 specimens observed as of December 28, 2015.
