 XXII. — APHIDES. 



Almost everyone who cultivates flowers has seen the 

 green Aphides or plant-lice, which are so troublesome 

 on the roses, sweet peas, verbena and other house and 

 garden plants. Perhaps a study of them and of their 

 habits will make them more interesting if not less an- 

 noying. 



With a dissecting needle or wooden tooth-pick trans- 

 fer one of these insects to the center of a glass slide 

 and with a pipette slowly and carefully drop a little alco- 

 hol on it. After a few minutes remove the alcohol that re- 

 mains by touching the drop with a piece of blotting 

 paper, which will absorb the liquid and if suflScient care 

 has been taken will leave the Aphis in a standing position.
