202 INSECTS INFESTING THE GRAPE. 



Fig. 186. — Angular-winged Katydid ; 1, tliu adult — color, 

 green ; la, the eggs — color, brownish or slate color ; Ih, the 

 young — colors, green and yellow ; 5, an egg parasite (the 

 Eupclurus mirabilis of Walsh) female, enlarged — colors, black 

 and yellowish ; 2a, the male, enlarged — color, metallic-green ; 

 26, eggs, showing holes from which these parasites had emerged. 



The eggs overlap each other (Fig. 186, 2b,) at one end and 

 are usually placed in two rows, side by side, but more rarely 

 in a single row. The number of eggs laid at one time varies 

 from two to thirty, and each female (Fig. 161, i,) deposits 

 about two hundred eggs. As soon as hatched, the young 

 grasshoppers (Fig. 186, lb, lb,) begin to feed upon the pulpy 

 part of the leaf. They do not pass through a quiet pupa state, 

 as butterflies and many other insects are known to do, but 

 continue active from the time they -leave the egg until they 

 die of old age or some other cause. Two broods are probably 

 produced in one season, the eggs of the last brood not hatch- 

 ing until the following Spring. Should this species ever 

 become numerous, a great amount of damage would be done 

 to the foliage of the trees or plants on which they feed.

Fig. 187. — Katydid — color, green. 



Note. — The above insect is frequently mistaken for the true 

 katydid {riatyphi/lluin coneaciim — Harris) which inhabits the 

 eastern part of this country, but has not, so far as I am aware, 

 been found in tliis State. By conqtaring Fig. 187 with Fig. 186, 

 1, the (litference Ijctween these two species is readily observable. 



Remedies. — No. 18 ; and also l\v eai)turing and destroying 

 the perfect insects.
