Rare Blue Frog Stuns Virginia Park Visitors

A rare blue American green tree frog has become a local attraction at Huntley Meadows Park in Alexandria, Virginia, drawing numerous nature enthusiasts and photographers. This unique amphibian, scientifically known as Dryophytes cinereus, displays a rare blue coloration attributed to axanthism, a condition where yellow pigmentation is reduced or absent. While green tree frogs are common in the Mid-Atlantic, a blue variant is exceptionally rare, with some experts likening it to spotting an albino squirrel. Scientists are intrigued by this phenomenon, as axanthism is not widely documented in wild green tree frog populations. Potential causes include diet, environmental factors, or genetic mutations. The D.C. region, particularly areas east of Interstate 95, has emerged as a surprising hotspot for these blue frogs, a geographic pattern that remains a mystery to researchers. This has led to a surge of observations through community science platforms like iNaturalist, significantly contributing to the understanding of this rare trait. The presence of such an exotic-looking creature in suburban Alexandria brings joy and wonder to those who seek it out.
