Cameraria hamadryadella
Solitary Oak Leafminer, Solitary Oak Leafminer Moth
Cameraria hamadryadella is a small leaf-mining moth in the family Gracillariidae, widely distributed across temperate North America. The larvae feed exclusively on oak (Quercus) species, creating distinctive mines within leaves. Adults are active in spring with typically two generations per year, though a facultative third generation may occur in warm years. Population dynamics are strongly influenced by host plant phenology, particularly the timing of autumn leaf fall, which can account for more than 50% of mortality in years with early leaf drop.
