The photos at top left, bottom left and bottom right show one of two specimens captured on the night of 19 April 2005.  The photos at center left and center right are of the other specimen captured on the night of 19 April 2005.

Feralia jocosa has a green forewing, slightly darker and tinged with gray in the median area.  The green ground color may vary from quite a bright grassy green (as in the center pair of photos above) to a pale blue-gray green (as in the top left and bottom photos).  The reniform and orbicular spots are clearly defined, light green in the center, surrounded by white, with a black outline.  The postmedial line is a double black line, filled with white, forming somewhat angular scallops.  Unlike Feralia comstocki (10008), F. jocosa does not have prominent black blotches around the reniform spot.  The head and thorax are predominantly green.  The fringe is checkered black and pale green to white.  The hindwing is brownish gray with green in the fringe. 

The larvae of Feralia jocosa feed on a wide variety of evergreen trees, including balsam fir, and various spruce, pine and hemlock species.  For my general area, Handfield (1999) indicates an adult flight season from mid-April to early June.  I have rarely observed this species, however, perhaps because of the relative scarcity of evergreen trees in my immediate vicinity. 

My records of observations of Feralia jocosa (each date representing "the night of") are in the table below:
