172 DIFFERENT SPECIES OF INSECTS 



This species, however, is not confined to the 

 hot-house only, but is commonly found upon 

 plants growing in the open air, as also upon 

 flowers. These insects are often very numerous 

 upon the flowers of pinks and carnations. 



The Thrips sometimes attack the young shoots 

 of Vines growing in the open air, especially those 

 of weak Vines, or Vines newly planted. 



If young shoots chance to receive any injury 

 by late spring frost, the tender part of the leaf 

 will immediately curl up, and change to a dark- 

 brown colour ; and in this state the Thrips ge- 

 nerally attack them with great greediness, es- 

 pecially the white Sweetwater and white Muscadine 

 kinds. These sorts are generally planted against 

 common walls. 



The Thrips, however, are seldom injurious to 

 Vines growing in the open air, except in the 

 spring ; and to those in the hot-house they are 

 most hurful when the grapes are nearly ripe. They 

 attack the bunches as well as the leaves, and 

 commonly prey upon the extremities of the berries, 

 but more particularly at the end next the foot-stalk. 

 In white grapes, the part of the berry injured 

 changes to a dark colour, the foot-stalk turns black, 

 and the berry withers. 



3. The Aphis. The Aphides are, I believe, the 

 most numerous of all the insect tribe. This species 

 infests the brawny oak, as well as the minutest 

 weed. What are called honey-dewsin the summer, 

 are occasioned by this species of insect. The
