and when full-grown is nearly % inch 

 long. The caterpillar and its injury 

 resemble those of the greenhouse leaf 

 tier. The moth has red bands across 

 the wings, from which it derives its 

 name. 



Treatment. — Same as for green- 

 house leaf tier (p. 5).

HONEYSUCKLE 



Fall Webworm 



The fall webworm (Hyphantria cunea 

 (Drury)l is widely distributed and pri- 

 marily a pest of many shade and forest 

 trees. It occasionally infests woody 

 shrubs, and when food is scarce it may 

 invade the flower garden. The caterpillars 

 spin a tentlike web at the ends of the 

 branches, enclosing the foliage on which 

 they feed (fig. 83). When the cater-

pillars are numerous, entire branches 

 may be enclosed in these unsightly, 

 whitish webs. The caterpillar is hairy, 

 with long grayish-brown hairs arising 

 from black and orange spots and shorter 

 hairs between. It is about an inch long 

 when full-grown and has a broad brown- 

 ish stripe along the back. In the more 

 northern States there is one generation, 

 occurring after midsummer. Farther 



south there are two generations, the first 

 late in the spring and the second later in 

 the summer. The thin cocoons are 

 spun in protected locations or in the 

 soil. From these the satiny-white 

 moths emerge and lay their eggs in 

 masses on the leaves. 



Treatment. — Cut off the web nests 

 containing the caterpillars while they 

 are still small, and burn or destroy them. 

 If they are abundant, spray or dust with 

 lead arsenate before much of the foliage 

 has been enclosed in the webs. 



Honeysuckle SawMy 



The larvae of the honeysuckle sawfly 

 (Zaraea inflata Nort.) occasionally strip 

 the leaves from honeysuckle in the 

 spring. The larvae resemble hairless or 

 naked caterpillars and are about an 

 inch long when full-grown. They are 

 somewhat grayish, with several yellow- 

 ish stripes along the body and a row of 

 black spots down the back. After their 

 feeding is completed they spin coccons 

 in the soil and remain there until the 

 following spring, when the wasplike 

 adults emerge to lay eggs for a new 

 generation. 



Treatment. — Spray with lead arse- 

 nate to poison the feeding larvae. 

 Spraying or dusting with derris would 

 very likely be effective against the young 

 larvae. 



Angular-Winged Katydid 



The angular- winged katydid (Micro- 

 centrum retinerve (Burm.)), which is one 

 of the so-called long-horned grasshop- 

 pers, feeds on the foliage of trees and 

 certain shrubs. It occasionally de- 

 posits its eggs on the edges of leaves or 

 on twigs or branches of various plants 

 such as honeysuckle, rose, and aster. 

 The oval, flat, scalelike eggs (fig. 8-4) 

 are placed in neat rows so that they 

 overlap; they are occasionally mistaken 

 for scale insects. This insect is dis- 

 tinguished from other grasshoppers by 

 its very long "feelers," or antennae. 

 Usually it is not a destructive pest. 



Treatment. — Remove and destroy 

 portions of the plants bearing the eggs.
