SNAPDRAGON 

 Rose Budworm 



The buds of snapdragon, rose, del- 

 phinium, columbine, and other garden 

 flowers are often eaten into by the 

 caterpillar of the rose budworm (Pyrrhia 

 umbra (Hufn.)), The adult is known as 

 the bordered sallow moth. Two dis- 

 tinct forms of caterpillars occur: one is 

 greenish, spotted with black tubercles 

 and prominent. dark, longitudinal 

 stripes, whereas the other has whitish- 

 orange markings on the back. 



Treatment. — Remove infested buds 

 as soon as noticed. Spray or dust with 

 lead arsenate if the plants are heavily 

 infested. 



Black Stinkbus 



The black stinkbug {Cosmopepla hi- 

 maculata (Thorn.)) is a plant-feeding 

 bug which attacks such flowering plants 

 as snapdragon, beardtongue, columbine. 

 and verbascum. By sucking the plant 

 juices this insect stunts bud clusters 

 and deforms individual buds. It is a 

 small, shining bug, about % inch long, 

 conspicuously colored with black and 

 red. It overwinters as an adult in 

 protected places. The name is derived 

 from its disagreeable odor. 



Treatment and prevention. — Same 

 as for tarnished plant bug (p. 35).

SPIREA 



Oblique-Banded Leaf Roller 



The foliage and flower buds of roses 

 and the leaves of spirea are occasionally 

 fed upon by the caterpillars of the oblique- 

 banded leaf roller (Archips rosace- 

 ana (Harr.)), also called the rose leaf 

 tier. This insect also feeds on aster, 

 carnation, geranium, honeysuckle, and 

 verbena. The caterpillar conceals it- 

 self by rolling the leaf upon which it is 

 feeding and also ties the terminal leaves 

 together, thus marring the plant and 

 interfering with its normal growth 

 (fig. 142). It varies from yellowish to 

 pale green and becomes % inch long 

 when mature. Two generations appar- 

 ently occur annually, one in the spring 

 and the other late in the summer.
