of genera, which contain species that differ in appearance 
from other Noctuids, the larvae of many being hairy like 
those of Arctiids. The fore wings of the moths are gener¬ 
ally light gray with dark spots, and in many species have a 
dagger-like mark near the anal angle. On this account these 
moths have received the name Daggers. 
The Ochre Dagger, Acronycta morula (Ac-ro-nyc'ta mor'u- 
la).—This moth (Fig. 372) is pale gray with a yellowish 
tinge. Besides the black line 
forming part of the dagger 
near the anal angle of the 
fore wing, there is a similar 
black line near the base of 
the wing, and a third near 
the outer margin between 
veins V, and V a . The larva 
feeds on elm and basswood. When full grown it is mottled 
brown and greenish like the bark, it is clothed with but few 
scattered hairs, and has a 
hump on the first, fourth, and 
eighth abdominal segments. 
The American Dagger, Ac - 
ronycta antericana (Ac-ro-nyc'¬ 
ta a-mer-i-ca'na).—This is a 
gray moth resembling in its 
general appearance the pre¬ 
ceding, but with the black 
lines on the fore wings much 
less distinct. Its larva, how¬ 
ever, is very different (Fig. 
373). This larva looks like an 
Arctiid, being densely clothed 
with yellow hairs. But these 
, hairs are scattered over the
