Tue Insect Fauna OF THE GENUS CRATAEGUS 1073 
Saturniidae 
10 Fabr., Automeris 
The eggs of Automeris io are not uncommon on the under side of haw- 
thorn leaves in late June and in July. They are very characteristic and 
conspicuous. A cluster of eggs may consist of a dozen or more, each 
large and creamy white with a dark blue dot on the distal end. The 
larvae feed in colonies on the foliage during July, August, and September. 
They are at first dark, then green, and are always covered with a mass of 
dark, stinging spines. 
Arctiidae 
caryae Harris, Halisidota (Hickory tussock moth) 
The black-and-white-tufted caterpillars of the species Halisidota caryae 
are fairly common on native hawthorns during August. 
tesselaris A. and S8., Halisidota 
The caterpillars of Halzsidota tesselaris are similar to those of H. caryae 
and are found occasionally on the foliage with them, but are not so 
common. 
textor Harris, Hyphantria (Fall webworm) 
A single colony of larvae of Hyphantria textor was feeding on Crataegus 
pruinosa on July 31, 1918. An egg cluster which was probably of this 
species hatched on June 19, and the young larvae fed on C.. punctata leaves 
for a few days and then died. 
Noctuidae 
americana Harris, Acronycta 
The larvae of Acronycta americana are green, with an abundant covering 
of yellowish white hairs and a few long pencils of black hairs. They were 
found feeding on the leaves of native hawthorns in late June and July. 
The species is not common. 
dactylina Grote, Acronycta 
The larvae of Acronycta dactylina are entirely covered with yellowish 
white hairs and have three long pencils of black hairs. They were feeding 
on the foliage of Crataegus punctata from August 15 to September. The 
Species is not common. 
luteccoma G. and R., Acronycta 
The larvae of Acronycta luteicoma are black, with tufts of white hairs 
on segments 3 to 6 and tufts of black hairs on the other segments. They 
were found feeding on Crataegus punctata leaves from June 23 to July 22. 
The species is not common.
