The Coral-fronted Threadtail (Neoneura aaroni) is a member of the family Protoneuridae and within the U.S. occurs only in Texas. It is also found southward into parts of Mexico. Most Texas records have been in the Hill Country of the central part of the state, but the species has also been found along the Rio Grande. The shots here of a male in flight and of a pair in tandem were taken along the banks of the Rio Grande in San Ygnacio, Zapata Co., Texas in May, 2005. A very large mayfly hatch had occurred along the river and the tandem pairs were seen ovipositing into the debris created from thousands of dead mayflies collected near the shore. These photos were all digital captures with a Canon EOS 1D Mark II and an EF 300mm F/4 L IS lens and 2X extender and 580EX flash.
