originally described as Yponomeuta atomocella Dyar, 1902
Described by Forbes (1923) as Prays atomocella (1)
Explanation of Names
Author: Dyar, 1902
With the forewing having the black spots rather large (compared to those of Yponomeuta) and the apical fringe rust colored (versus white in Yponomeuta), this moth is diagnosed as Yponomeutidae: Prays atomocella. -- Terry Harrison, 24 May, 2009
It has one generation per year. In early spring, the larva feeds inside a new shoot of hoptree, Ptelea trifoliata (Rutaceae); then it pupates and emerges as an adult, in which stage it spends the rest of the year until mating and laying eggs the following spring. -- Terry Harrison, 24 May, 2009
The only native Nearctic species of the genus Prays
Terry Harrison argues that the correct name for this species is Prays atomocella on
