BENEFICIAL ORCHARD INSECTS 



G.L 

 Department

 of Entomology 



Although there are many insects which may be observed in any 

 given orchard, many are of little or no consequence. Most orchard- 

 ists hopefully are able to recognize the harmful species, or the 

 damage done by them, but few are aware that beneficial insects are 

 also at work in their orchards. The following information, descrip- 

 tions and pictures are provided in hopes that some of the more com- 

 mon beneficial insects might be recognized and protected by orchard- 

 is t s . 



Assassin bugs (Fig 1) are about 1/2" long or longer, usually black 

 or brown with an abdomen which is often widened at the middle. A 

 few members of this family are known as "kissing bugs" and will bite 

 man to obtain blood; however, most are predacious on other insects 

 such as honeybees, leafhoppers and caterpillars. Many will inflict 

 a painful bite if carelessly handled. 



Ant lions (Fig 2) are of little or no consequence to orchardists, 



since the larvae eat only ants and other ground crawling insects. 



However, the larvae are similar to those of the lacewings consid- 

 ered next (shown in Fig 3).
