| Moths of North Dakota |
Noctuoidea Notodontidae: Heterocampinae |
Lochmaeus bilineata (Packard 1864)
| Common name: Double-lined prominent Hodges #: 7999 Identification: Rfw 19.0 mm, transverse lines double, p.m. line with white filling especially strong in cells CuA2 and in the fold. Reniform spot a black bar or obscure. Eighth sternite of male with two large pits connected by a shallow depression, pits visible without removing scales. Members of the genus Lochmaeus can be separated from Heterocampa by having the terminal line reduced to a terminal spot in each wing cell, between veins rather than accenting veins. Members of the genera Heterocampa and Lochmaeus can be separated from Schizure by the constricted Rs cell on the hw. Similar species: 7920, 7928, 7930, 7983,7994, 7995, 7998, 8005, 9382. Distribution: southern Canada and United States east of the Rockies. Hosts: Larval feed on Elms- Ulmus, and Basswood- Tilia.
Note: the line drawing of the male eighth sternite in Forbes
(1948), p. 230, fig. 225, is inverted and from an oblique angle allowing
for the erroneous interpretation of possessing a sternal groove similar
to those of M. marthesia and H. obliqua. |
