|Common name: Double-lined prominent
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,
Distribution: southern Canada and United States east of the
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.
