Callophrys gryneus

Observation date: June 20, 2011
Submitted by: Appy-Brown
Specimen type: Photograph
Observation notes: Callophrys gryneus female ovipositing. One of two dozen found in many locations in a former pasture-reverting-to-shrubs. A population explosion led to 1000's of gryneus, 2003-2004 -- 10,000's throughout town. A population crash led to fewer and fewer sightings in the following years. In 2010, a few gryneus were found in at least two sites in this one pasture; where in 2011, multiple individuals were found in more than a dozen sites.
