Very rare. May be recognized by the wavy gray or greenish 

 line along the lateral border of the pronotum, the irregular yellow 

 patch extending from the middle of the lateral margin of the 

 pronotum upwards and forwards to the dorsum, and the yellowish 

 head. The posterior process does not quite reach the apices of 

 the tegmina which are hyaline in the center and brown at the bases 

 and tips. 



The life history is not known. 



Hosts: Black oak (Q. velutina), red oak, white oak.

 O. salamandra Fairmaire.

The largest and commonest species of Ophiderma in the State. 

 This is a large brown species with the dorsum rounded and very 

 pubescent with short black bristly hairs. The posterior process is 

 short and suddenly acute, not reaching the apices of the tegmina. 

 The tegmina are hyaline with the bases and costal areas strongly 

 punctate and the tips clouded with fuscous. A noticeable char- 

 acter of the tegmina is the prominence of the veins. The general 

 color is brown, mottled with green, the markings being very 

 irregular. 



The insect is very active and difficult to study in the field. The 

 life history is not known. 



Hosts : Red oak, white oak, scarlet oak, chestnut.

Very abundant. A small hairy species common on most species 

 of oaks throughout the Summer and apparently most abundant on 

 Quercus velutina. The species is one of the smallest of the 

 genus, light brown mottled with whitish or yellowish, dorsum 

 convex, very pubescent, posterior process short and blunt not 

 reaching tips of tegmina. The tegmina are hyaline with a median 

 black stripe and brown clouded tips. The males are smaller and 

 darker than the females.
