Explanation of Names
Dilaridae Newman 1853
From Old World genus Dilar Rambur 1838, a genus named after the Dílar region of Spain(1)
2 spp. of a single genus in our area(2), >70 spp. in 4 genera worldwide(3)

Adults resemble small brown moths: male antennae pectinate, female filiform; ovipositor recurved over abdomen:
N. americanus N. pulchellus
