coppery-brown wing covers, and is about 

 ji inch long. The sides and tip of the 

 abdomen are marked with white dots. 

 The beetles appear in June and are 

 numerous during July and August. 



Treatment. — Spraying the foliage 

 with lead arsenate at 1% times the 

 usual strength (p. 95) with a suitable 

 sticker such as wheat flour, or repeated 

 spraying with 5 ounces of derris powder 

 plus o l ( ounces of rosin residue added 

 to 10 gallons of water, will usually 

 give some protection. Pyrethrum will 

 kill such beetles as are hit by the spray. 

 Since the Department has several 

 publications on the life history, habits, 

 and control of this insect, anyone 

 interested in obtaining more detailed 

 advice should write directly to the 

 United States Department of Agri- 

 culture.

Abutilon Moth 



The caterpillar of the abutilon moth 

 (Anomis erosa Hbn.) somewhat re-

 walk with a looping motion. It is some- 

 times found in considerable numbers in 

 the flower garden feeding on abutilon

 discussion on the cabbage looper (p.

Treatment. — Same control as for the

HOLLY 



Holly Leaf Miner 



The tiny maggots of the holly leaf 

 miner (Phytomyza ilicis (Curt.)) mine 

 inside the leaves of American and 

 English holly. Each mine is winding 

 and narrow, but gradually increases in 

 width as the maggot develops. The 

 mines are plainly visible on the upper 

 leaf surface (fig. 81), where the mined 

 tissue turns to yellowish green. The 

 foliage on badly infested trees appears 

 unhealthy and somewhat faded. The 

 maggot, or larva, is pale yellow and 

 about V% inch long when full-grown. 

 The pupa is brown. The adult is a 

 small grayish-black fly, about Ko inch 

 long. The insect passes the winter 

 inside the infested leaves on the trees. 

 In the spring when the new leaves are 

 only partly grown the adults begin to 

 emerge. Emergence continues for about 

 2 or 3 weeks, and during this time the 

 flies deposit their eggs in punctures 

 made in the new foliage. This intro- 

 duced pest is widely distributed in the
