Hepialidae: Sthenopis purpurascens Eggs - Sthenopis purpurascens

Hepialidae: Sthenopis purpurascens Eggs - Sthenopis purpurascens
Turtle River State Park, Grand Forks County, North Dakota, USA
July 12, 2012
Size: Egg Diameter ~ 1 mm
Four-spotted Ghost Moth (0019) eggs are poppy seed-size and corn meal yellow when first laid. They roll easily, like ball bearings on a smooth surface. After several hours at room temperature about two-thirds of perhaps 300 yellow eggs that were laid changed color from yellow to black. I reckon that this color change may be a sign of egg fertility?
